i'm sure the linux audio community has something to contribute to

> DAFxTRa 2008 (DAFx Transformation RAting) is a new initiative
> promoted by
> MTG-UPF and DAFx-08 aimed at evaluating and comparing algorithms for
> audio effects.
> Our goal is to have the main evaluation in September 2008 during
> (http://www.acoustics.hut.fi/dafx08/) but to make it happen we need
> involvement of the audio effects research community.
> We do not know of any major initiative to compare audio effects
> algorithms, which might be the related to the difficulty of the
> evaluation task. It is hard because it requires standardized
> procedures for
> carefully controlled subjective experiments. But we believe
> that now is the time to try it, so we can all learn from the
> process and in
> turn improve our audio effects algorithms.
> Inspired by the success of MIREX in the evaluation of Music
> Retrieval algorithms, and having acquired some experience by
> organizing the
> audio description contest at ISMIR 2004-Barcelona, we want to
> promote a
> similar initiative for the digital audio effects community.
> However most audio effects tasks do not afford an objective
> measure of ground truth, like in MIR, and thus we have to define
> specific evaluation strategies. We want to do it by involving the
> developers of algorithms interested in participating and by specifying
> with them the evaluation process. The participants should learn
> from the
> process and the whole DAFx community should benefit from it.
> Our initial aims are the following:
> 1. Propose several audio effects categories. Initial proposal: time-
> pitch-shifting, source separation, morphing, distortion effects and
> 2. Select the categories for which there is a sufficient number of
> 3. Select sounds from Freesound (http://freesound.iua.upf.edu) to be
> used as test sounds for each category.
> 4. Define the evaluation procedure for each category.
> 5. Ask the participants to submit the transformed sounds (not the
> 6. Perform the evaluation both live at DAFx-08 and also online in
> 7. Publish the results of the evaluation.
> Our proposed time-line is:
> - 1st August 2008: Finalize categories and evaluation procedures
> - 30th August 2008: Submit transformed sounds
> - 1st-4th September 2008: Run life evaluations at DAFx-08 Conference
> - 10th-30th September 2008: Run on-line evaluations on the
> Freesound site
> - 15th October 2008: Publish the results
> If you are interested in participating or in getting involved in the
> process join the DAFxTRa mailing list
> (http://iua-mail.upf.es/mailman/listinfo/dafx-eval) for an open
> Results of the discussion and organizational details of the evaluation
> will be posted in a wiki (http://smcnetwork.org/wiki/DafxTRa2008)
> Your input and ideas will be most welcome.
