It is the process of creating new data from existing data (e.g. by adding noise). This is done to increase the size of the training data and to make the model more robust.</p>
<p>Recent work has created tools for performing data augmentation using the <a href="https://sonicscrewdriver.ebaker.me.uk">sonicscrewdriver</a> package for R. A guide to using these tools can be found here: <a href="https://medium.com/bioacoustica/generating-acoustic-training-data-in-r-with-sonicscrewdriver-774a440f5c6e">Generating acoustic training data in R with sonicscrewdriver</a>, and on the package's website: <a href="https://sonicscrewdriver.ebaker.me.uk/articles/augment-audio-data.html">Augmenting audio data in R with SonicScrewdriveR</a>. The later will be updated to reflect any future changes to the package.</p><p>The updated package is already on CRAN: <a href="https://cran.r-project.org/package=sonicscrewdriver">sonicscrewdriver R package</a>.</p>
<p>All of the generateX() functions (<a href="https://sonicscrewdriver.ebaker.me.uk/reference/generateNoise.html">generateNoise()</a>, <a href="https://sonicscrewdriver.ebaker.me.uk/reference/generateTimeMask.html">generateTimeMask()</a>, <a href="https://sonicscrewdriver.ebaker.me.uk/reference/generateTimeShift.html">generateTimeShift()</a>, more to come) in sonicscrewdriver are designed to operate on Wave-like objects (Wave or WaveMC from tuneR of their Tagged equivalents) or a list of Wave-like objects. Similarly, all of these functions return a list of Wave-like objects. This means you can combine these functions to create complex data augmentation pipelines.</p>

<br />
There are a number of recordings of this species in the BioAcoustica repository: <a href="http://bio.acousti.ca/classification/oecanthus-pellucens">recordings of Oecanthus pelluscens on BioAcoustica</a>.<br />
<iframe src="https://api.audioblast.org/standalone/embed/recording/?source=bio.acousti.ca&id=13454&embed=iframe&output=html5" style="border: none; width: 680px;"></iframe><br />
Like many tree crickets it has a certain translucent quality, and it is this that <a href="https://en.wikipedia.org/wiki/Giovanni_Antonio_Scopoli">Giovanni Antonio Scopoli</a> alludes to when giving it the specific name <i>pellucens</i>. Torre-Bueno's <i>A Glossary of Entomology</i> gives the definition:<br />
<blockquote class="tr_bq">
<b>pellucid, pellucidity, pellucid,</b> transparent, whether clear or coloured.</blockquote>
(This definition is somewhat incorrect, something transparent <b>is</b> clear, it can be coloured or colourless, but I digress)<br />
<br />
That Scopoli refers to this property is clear in the original description: "Caput album, subpellucens". Subpellucens is best translated as opaque.<br />

<br />
All very well, but so far not particularly interesting. The (minor for most) interest comes from an alternative definition of pellucid, here borrowed form the Oxford English Dictionary.<br />
<blockquote class="tr_bq">
Of music or other sound: clear and pure in tone.</blockquote>
Crickets in general are known for their pure bell like songs, and that of <i>Oecanthus pelluscens</i> is no exception. Shown below are three chirps from the recording above (time on x-axis, frequency on y-axis). This shows a strong resonance frequency, with three clear, regularly spaced, harmonics: a clear and relatively pure tone indeed.<br />

<blockquote class="tr_bq">
"Few country people today are acquainted with the Mole Cricket, but formerly, when presumably it was commoner, it went by such names as "Churr-worm" and "Eve-churr". These concern its strange jarring "note" which is heard chiefly during the evening in the spring." </blockquote>
<blockquote class="tr_bq">
- G. E. Hyde. (1961) Teach Yourself Entomology. The English Universities Press Ltd, London.</blockquote>
<br />
But what is a churr? The Oxford English Dictionary (OED) describes it as "expressive of a somewhat deeper and hoarser sound than chirr", and chirr as "to make the trilled sound characteristic of grasshoppers, etc."<br />
<br />
The Mole Cricket (in this case <i>Gryllotalpa gryllotalpa </i>- there are many others outside the UK) produces its churr in the evenings and nights, so Eve-churr seems appropriate. This vernacular name is shared, however, with the nightjar (<i>Caprimulgus europaeus</i>). As the name seems obsolete for both species the chances for confusion are currently minimal. Nightchurr is also an obsolete (regional) name for both these species (OED).<br />
<br />
The OED also distinguishes a chirr from a chirp, the chirr being "often nearly equivalent to chirp , but properly expressing a more continuous and monotonous sound." As a side-note many authors in bioacoustics have followed <a href="http://bio.acousti.ca/content/proposal-new-term-%E2%80%98echeme%E2%80%99-replace-%E2%80%98chirp%E2%80%99-animal-acoustics">Broughton (1976)</a> in using the precisely defined neologism <i>echeme</i> in place of chirp.<br />
<br />
There are no doubt other regional names for the Mole Cricket in the UK, John George Wood in his 1866 book <i>Homes without hands: being a description of the habitations of animals, classed according to their principle of construction</i> gives the delightful Croaker.<br />
<br />
The status of the Mole Cricket in the UK has not improved and it is confined to the New Forest. Until recently the only confirmed recent record was several sound recordings, one of which is below.<br />
<iframe src="https://api.audioblast.org/embed/recordings/recording/?source=bio.acousti.ca&id=13631&output=html5" style="border: none; width: 100%;"></iframe>Edhttp://www.blogger.com/profile/14569326774736717270noreply@blogger.comtag:blogger.com,1999:blog-2063119946997933431.post-16633388783240491682020-01-09T13:35:00.001+00:002020-01-09T13:35:33.105+00:00On stridulation, and dictionaries...Over the Christmas period I pulled out a few entomological and general science dictionaries to see how much bioacoustic terminology was present. The definitions of stridulation I found (with comments) are provided below, and there are some striking errors (at least for those who like their insects in the correct Order), as well as some minor issues.<br />
<br />
The accuracy of the definitions seems to improve with the specificity of the work. The less likely you are to need the dictionary the more likely you are to have one with a correct definition?<br />
<h3>
A Glossary of Entomology (Torre-Bueno, 1962 third printing)</h3>
<div>
<blockquote class="tr_bq">
"<b>stridulating organs</b>, parts of the insect structure which are used in making sounds; in general, one part is a file-like area and the opposing one a scraper or rasp (Imms)."</blockquote>
<blockquote class="tr_bq">
"<b>stridulation</b>, in insects, the sound produced by rubbing one surface or one structure upon or against another, both being suitably roughened; the act of stridulating or making creaking sounds."</blockquote>
This definition seems concise and is hard to argue with. </div>
<h3>
Oxford Dictionary of Science (4th Edition, 1999)</h3>
<blockquote class="tr_bq">
"<b>stridulation</b> The production of sounds by insects rubbing one part of the body against another. The parts of the body involved vary from species to species. Stridulation is typical of the Orthoptera (grasshoppers, crickets, cicadas), in which the purpose of the sounds is usually to bring the sexes together, although they are also used in territorial behaviour, warning, etc."</blockquote>
A major taxonomic issue here including the cicadas within the Orthoptera. Cicadas also produce sound by tymbalisation rather than stridulation. No note of the specialisation of the parts involved in sound production, but forgivable given the broad scope of the dictionary. Bonus point for mentioning the multiple purposes of sound production.<br />
<h3>
Henderson's Dictionary of Biological Terms (12th Edition, 2000)</h3>
<blockquote class="tr_bq">
"<b>stridulating organs</b> n. special structures on various parts of the body of certain insects such as grasshoppers, crickets and cicadas, which produce the characteristic "song" of these insects." </blockquote>
<blockquote class="tr_bq">
"<b>stridulation</b> n. the characteristic sound made by grasshoppers, crickets and cicadas."</blockquote>
Again cicadas are a problem, although this time they are at least not placed within the Orthoptera. The specialisation of the structures is mentioned, although no mention of their movement against each other.<br />
<br />
<h3>
<b>A Dictionary of Entomology (Gordh & Headrick, 2001)</b></h3>
<blockquote class="tr_bq">
"<b>STRIDULATING ORAGNS</b> Hardened parts of the insect body that are used in making sounds. Typically one part is a file-like surface and the opposing one a scraper or rasp (Imms)."</blockquote>
<blockquote class="tr_bq">
<b>"STRIDULATION </b>(Latin, <i>stridulus</i> = creaking, squeaky; English, -tion = result of an action. Pl., Stridulations.) 1. Friction of rigid parts on modified surfaces. Insects: The sound produced by rubbing a series of hard projections (spines, Acanthae) against a file-like surface, Stridulatory methods of acoustical communication are widespread in the Insect and probably the most generally used form of sound communication. Anatomy of a system consists of a Pars Stridens which forms a rasp (file) composed of tubercles and a Plectrum which forms a scraper (Strigil). 2. The act of stridulating or making creaking sounds."</blockquote>
This is about as comprehensive as one could expect in a dictionary. Not all stridulation in insects is by spines or tubercles, sometimes ridges on the integument are used, but this point seems relatively minor.Edhttp://www.blogger.com/profile/14569326774736717270noreply@blogger.comtag:blogger.com,1999:blog-2063119946997933431.post-78476895309316654442019-11-09T17:40:00.001+00:002019-11-09T21:23:13.742+00:00A quote for those working on ontologies and controlled vocabularies"Two dangers face the student seeking to rationalize and codify a terminology that has grown up empirically and that is beginning to differentiate regionally or according to faculty or in other ways - as must always tend to happen. One danger is that of legislating prematurely and clumsily for hypothetical future requirements; the other is a too easy-going and long-sustained attitude of <em>laissez-faire</em> arising from wishing to let the mud settle before trying to penetrate the shadows of often chaotic and obscure usages. If the former danger must always be borne in mind, the later is more insidious; while we wait for the mud to settle, divergence may be increasing, and we may be faced with the need to cure what we might have prevented."<br />

These allow recordings from BioAcoustica to be embedded in other webpages, and perhaps even the online versions of scientific papers.<br />
<br />
As an example below is the sound recording that led Klaus Gerhard-Heller and I to describe the species <i>Horatosphaga raggei </i>(<a href="http://bio.acousti.ca/node/50819">Heller and Baker, 2018</a>).<br />

As this is in beta, there are likely to be issues, and much of the interface lacks polish. Each recording on BioAcosutica will have an Embed link under the recording, which will take you to a page with several embed options (the page for the above recording is <a href="https://api.audioblast.org/embed/?source=bio.acousti.ca&id=10298">here</a>).

<div>
Dear all, </div>
<br />
<div>
It is my pleasure to announce the contest <strong>>spectro(2018)</strong>, a friendly and informal contest for the best spectrogram generated with R code.</div>
<br />
<div>
The spectrogram is a 2D/3D key visualisation tool for bioacoustics, ecoacoustics and other sound related disciplines. The spectrogram is not only useful for science, it can also be a nice graphical object with delicate shapes and colours. </div>
</div>
The aim of this contest is to share the beautiful sounds, R codes and spectrograms you may have in your files so that it can help others to produce nice graphics and figures.</div>
<div class="2" style="font-family: arial, helvetica, sans-serif; font-size: 12pt;">
<br /></div>
<div class="2" style="font-family: arial, helvetica, sans-serif; font-size: 12pt;">
But overall, the idea is to join science, fun, and maybe the arts!</div>
<div class="2" style="font-family: arial, helvetica, sans-serif; font-size: 12pt;">

Sadly the timing of the launch of BioAcoustica was very close to the Scratchpad Lead Developer leaving the Natural History Museum (the <a href="https://ebaker.me.uk/node/148">BioAcoustica Database Paper</a> was their last NHM publication).<br />
<br />
Since that time the Scratchpads have had little love (apart from some work I have done to keep them alive) and seem to be slowly decaying. This is set to change soon (I am led to believe, although not for the first time) with new developer attention. This is always a risk of building a project on top of infrastructure maintained and developed elsewhere. (The upside is that BioAcoustica development has leveraged existing infrastructure to manage biological taxonomies, DarwinCore compliant specimens, literature, etc).<br />
<br />
Completely separating from the Scratchpads project, at least for now, is still undesirable. Recently the NHM team have started attending to the Scratchpads servers, and replicating the server environment outside the NHM introduces issues for future maintenance once the Scratchpads receive the care they deserve. (Although I have tested getting the infrastructure running on an external cloud hosting provider - it works - to ensure we have all bases covered).<br />
<br />
So assuming future development of the Scratchpads will resolve the issues we have been having with occasional downtime and that fixes and that new features/infrastructure should be coming, what can we do to improve the current situation?<br />
<br />
Aside from downtime the main issue that people have reported to me is slow file downloads. BioAcoustica is bandwidth heavy - we prefer wave files to MP3 files (for science reasons) for many taxa, and many of the files (particularly soundscapes) are large, often in the gigabyte range.<br />
<br />
A quick test of downloading files from the Scratchpad server and the recently launched <a href="https://www.digitalocean.com/community/tutorials/an-introduction-to-digitalocean-spaces">Digital Ocean Spaces</a> revealed that we could potentially increase file bandwidth by a factor of 10. Shifting high bandwidth reads from the Scratchpads to the cloud clearly offers benefits to BioAcoustica users (faster load time), particularly if they are using the R interface to work with a large number of files.<br />
<br />
Another issue this addresses is file backups. While the Scratchpads databases have a regular backup schedule (daily, weekly, monthly, yearly) the file backups are held only for 30 days, which has led to previous issues when nobody noticed until too late that the files had gone from their site. An automated process of copying files to the cloud as they are uploaded has the potential to allow for a more long-term backup mechanism.<br />
<br />
So where are we now? If you visit a recording page on BioAcoustica (e.g. this <a href="http://bio.acousti.ca/content/91gryllotalpa-gryllotalpa">Mole Cricket</a>) then there is a good chance that the file downloaded to display the webform is currently being served from Digital Ocean rather than the Scratchpad directly. Similarly the download link will more likely than now use the same source.<br />
<br />
What's coming next? Over the next day or so the R interface will be updated to use Digital Ocean for file transfers. This change will happen silently and will not affect users (besides saving them time). In the near term the R package will be updated so that the metadata services it relies on will also be served from the cloud, allowing the R (read only) interface to function even during times of Scratchpad downtime.Edhttp://www.blogger.com/profile/14569326774736717270noreply@blogger.comtag:blogger.com,1999:blog-2063119946997933431.post-85586729295175204562017-11-25T15:10:00.001+00:002017-11-25T15:18:17.811+00:00From scientific sound collection to entomological erotica. Part 1.The <a href="http://bio.acousti.ca/">BioAcoustica</a> project goes from strength to strength. Recently <a href="https://www.researchgate.net/profile/Klaus-Gerhard_Heller">Klaus-Gerhard Heller</a> and I published a <a href="https://ebaker.me.uk/node/193">new species</a> of the bush-cricket <i>Horatosphaga</i> that Klaus-Gerhard first identified from a <a href="http://bio.acousti.ca/node/10298">recording</a> I had made available on the platform. The species was named in honour of David Ragge, who worked on bush-crickets at the Natural History Museum (NHM) in London for many years, as well being the founder of the NHM's library of recorded wildlife sounds.<br />
<br />
Making the NHM sound collection freely available allowed Klaus-Gerhard to identify the potential new species - and after I re-prepared the future holotype to expose the stridulatory file it could be confirmed easily enough. The openness led to a new collaboration.<br />
<br />
The first taxonomic group that we have made data available for was the <a href="https://ebaker.me.uk/node/173">Gryllotalpidae</a> - in part because of the status of <i>Gryllotalpa gryllotalpa </i> in the UK is of interest, and in part because the NHM also has casts of some of the acoustic burrows made by males.<br />
<br />
At the recent <a href="https://www.orthoptera.org.uk/content/day-talks-grasshoppers-related-insects-1-november-2017">Orthoptera Special Interest Group</a> (SIG) of the <a href="https://www.royensoc.co.uk/">Royal Entomological Society</a> I was approached by <a href="http://www.wildlife-film.com/-/CliveHuggins.htm">Clive Huggins</a> who informed me that I was listed in the credits of <a href="https://en.wikipedia.org/wiki/The_Duke_of_Burgundy">The Duke of Burgundy</a> - an art film with entomology as an important plot point, and it appears a good amount of slightly unusual erotica. Indeed The Guardian starts one review with the following paragraph:<br />
<br />
<blockquote class="tr_bq">
<span style="font-family: inherit;">"<a class="u-underline" data-component="auto-linked-tag" data-link-name="auto-linked-tag" href="https://www.theguardian.com/film/the-duke-of-burgundy" style="border-bottom-color: rgb(220, 220, 220); border-bottom-style: solid; border-bottom-width: 0.0625rem; color: #005689; cursor: pointer; text-decoration: none !important; transition: border-color 0.15s ease-out;">The Duke of Burgundy</a><span style="background-color: white; color: #333333;"> is the most tender love story you'll see in which a woman forcefully urinates in her lover's mouth."</span></span></blockquote>
<br />
This obviously needs to be checked out. The only issue was I had completely forgotten about supplying the recordings. I initially assumed they were just taken from <a href="http://bio.acousti.ca/">BioAcoustica</a> - but the film was made just before <a href="http://bio.acousti.ca/">BioAcoustica</a> went live.<br />
<br />
Digging through old emails I discovered when the film crew got their hands on the recordings. Before BioAcoustica was released to the public we had to get permission from the NHM to release the sound recordings under an open licence (Creative Commons Attribution), which I managed to arrange. At about this time I was passed an email from a film company via George Beccaloni (at the time NHM Curator of Orthopteroid insects) from someone who was after recordings we had of various <i>Gryllotalpa</i> species. The reason I had no recollection of the storyline was due to not having many details about the film. Indeed the only thing I did now follows here:<br />
<blockquote class="tr_bq">
<span style="font-family: inherit;">"We'd be using as part of a film soundtrack - it's the story of two entomologists ( sort of!) - in one scene they listen to Mole Crickets...."</span></blockquote>
So that's how George and I ended up being credited in The Duke of Burgundy.<br />

It is the first data paper to come from the NHM Sound Archive digitisation project. The archive itself is part of the inspiration behind the <a href="http://bio.acousti.ca/">BioAcoustica</a> project (<a href="http://dx.doi.org/10.1093/database/bav054">Baker et al, 2015</a>). The paper covers the Mole Crickets (Orthoptera: Gryllotalpidae).<br />
<br />
The paper is certainly modest compared to other forthcoming data papers on the NHM's collection of Orthoptera sounds (and even our previous paper on <a href="http://dx.doi.org/10.3897/BDJ.3.e5792">African cicada songs</a>), however it is of interest due to the fact we have plaster casts of two of the species singing burrows to supplement the sound recordings.<br />
<br />
<i>Gryllotalpa vineae </i>was first described by Bennet-Clark in 1970 who later, published on the acoustic properties of its singing burrow (see figure).<br />

<br />
The existence of the singing burrow cast and the recordings has previously been limited to those with knowledge of the NHM's Orthoptera collection and those who have read Bennet-Clark's papers. To aid access (and hopefully increase interest) in these items the burrow casts we have (of <i>Gryllotalpa vineae </i>and also <i>Gryllotalpa gryllotalpa</i>) have been laser scanned. 3D models of the burrows have been made available on the NHM's Data Portal.<br />
<br />
The paper has more details: <a href="http://dx.doi.org/10.3897/BDJ.3.e7442">Natural History Museum Sound Archive I: Orthoptera: Gryllotalpidae Leach, 1815, including 3D scans of burrow casts of Gryllotalpa gryllotalpa Linnaeus, 1758 and Gryllotalpa vineae Bennet-Clark, 1970</a>.<br />
