soundsoftware: software sustainability for audio and music researchers
DESCRIPTION
Presented at the SoundSoftware 2012 Workshop: http://soundsoftware.ac.uk/soundsoftware2012 Sustainable and reusable software and data are becoming increasingly important in today's research environment. Methods for processing audio and music have become so complex they cannot fully be described in a research paper. Even if really useful research is being done in one research group, other researchers may find it hard to build on this research - or even to know it exists. Researchers are becoming increasingly aware of the need to publish and maintain software code alongside their results, but practical barriers often prevent this from happening. We will describe the Sound Software project, an effort to support software development practice in the UK audio and music research community. We examine some of the the barriers to software reuse, and suggest an incremental approach to overcoming some of them. Finally we make some recommendations for research groups seeking to improve their own researchers' software practice.TRANSCRIPT

Who (and why) are we?
EPSRC-funded four-year project, 2010–2014:
Run from the Centre for Digital Music at QMULServing the whole UK audio and music research community
Supporting the sustainable development and use of software and data to enable high quality research
Better science through better handling of software and data

Reproducible researchResearch used to be “reproducible” from the paper alone.This is no longer possible: too complex, the paper is not enough
Hence “Reproducible Research”:The paper – ideally Open AccessThe software – ideally Open SourceThe data – ideally Open Dataall bundled and published together
In audio and music research, few people do this. Why?

Why don't we publish code & data?Our survey suggested:
– Lack of time– Copyright restrictions– Potential for future commercial use
Other factors (UK Research Information Network, 2010):– Lack of evidence of benefits– Culture of independence or competition– Quality concerns (self-taught programmers)
Also: it takes effort early in the research cycle;hard to find time/motivation after the paper is published

Does this cut both ways?Can we improve quality by helping people prepare to share?

What can we do to help?
We’re taking a bottom-up approach:– aid incremental improvements to development practiceby– identifying specific barriers to publication and reuse,
that are relatively straightforward to addressSo we hope to:
– increase perception among researchers that code is something you can work on together, that can be reused
– prepare the ground for reproducible publication

Barriers to publication and reuse
– Lack of education and confidence with code– Lack of facilities and tools– Lack of incentive for publication– Platform incompatibilities
These are barriers to publication of code.Pilot data-management project at C4DM (to be discussed this afternoon) to feed into future work on data.

Barrier: Lack of confidence in codeIssue:Researchers largely self-trained in software development
Our approach:– Training in software development specifically for
researchers– Relatively small amounts of training can pay off
Autumn School, Software CarpentryWorkshops and tutorials around ISMIR and DAFx this year

Barrier: Lack of facilities and toolsIssue:Researchers don’t use code hosting / version control
Our approach:– Code site: http://code.soundsoftware.ac.uk– Focus on audio and music research– Public and private projects– Link publications with code– Simplified tools, e.g. EasyMercurial, http://easyhg.org
![Page 18: SoundSoftware: Software Sustainability for audio and Music Researchers](https://reader033.vdocuments.net/reader033/viewer/2022051817/54876ba6b47959f60c8b53fe/html5/thumbnails/18.jpg)

Projects and users of the code site

Barrier: Lack of incentive
Issue:Software not well recognised as research output
Our approach:– Link publications to code on the code site– Increase likelihood of code users discovering your papers– Ensure users know how to cite your work– Increase take-up / impact of your research
![Page 21: SoundSoftware: Software Sustainability for audio and Music Researchers](https://reader033.vdocuments.net/reader033/viewer/2022051817/54876ba6b47959f60c8b53fe/html5/thumbnails/21.jpg)
Barrier: Platform incompatibilities
Issue:Many different platforms and development tools in useSome are not available to all possible users (e.g. MATLAB)
Our approach:– Plugins where possible (e.g. Vamp for SV)– Take advantage of existing ecosystems
![Page 22: SoundSoftware: Software Sustainability for audio and Music Researchers](https://reader033.vdocuments.net/reader033/viewer/2022051817/54876ba6b47959f60c8b53fe/html5/thumbnails/22.jpg)
Suggestions for research groups
Aim at easy training targets; researchers may know less about coding than you'd think!– Program structure, arranging code across files etc
Insist on use of version control– Use what you have available, or code.soundsoftware.ac.uk
Turn code into plugins or components in modular systems– Latch onto the existing ecosystems of popular applications
Encourage collaborative development– Papers often co-authored, why not code?– Create an environment of confidence about sharing
