First, let me thank all my friends and colleagues in the FOSS community for coming out so strongly in support to my call for help on this matter. You guys rock!
Yesterday evening there was a mail from Dr Mandar Mitra (of ISI, Kolkata and IOTA Board member), wherein he posted counter arguments to Shri Anindya Banerji’s (the multimedia expert whose comments on inadequacy of FOSS tools for CBT development lead to this series of posts). Dr Mitra also asked from Mr. Banerji to clarify further on his comments.

This is with reference to the problems outlined by Shri Anindya Banerjee. I have first-hand experience only with Audacity and I found the list of problems very imprecise (details below). Perhaps Shri Banerjee could further clarify what he meant?
I think your suggestion that a small CBT be prepared as a proof of concept by competent and interested persons is an excellent one. If such a CBT can
be put together, that will be the best possible refutation of complaints about the capabilities of open source tools. If it cannot be done within a reasonable time frame, then we must decide whether the CBT itself is more important for IOTA than the means by which it is created.
> Audacity (as a substitute
> of Audition)
> Codecs are very poor
Poor in terms of supported formats? Audio quality of encoded file? What format were you decoding from / encoding to?
> Conforming process frequently crashes
What is a conforming process? I have been using Audacity for several years now, and cannot recall a crash.
> MP3 cannot be edited properly
What problem did you face? Again, I have used Audacity to edit mp3 files without issues.
> Unsafe rendering
What does unsafe rendering mean?
> Cannot be converted into MP3 properly
I usually do my editing on wav files, and use lame separately to encode to mp3. I know audacity can be set up to use lame directly.
> Too few tools to operate
What tools were you looking for that you did not find?
> Recording in full duplex cannot done properly
What is recording in full duplex? Playback during recording? What “improper” behaviour did you observe? In any case, for archival quality recording, you want to leave the processor as lightly loaded as possible. When I feel really uptight about this, I switch to single user mode (telinit 1) and do my recording using arecord, and edit later using Audacity.
> Dubbing facility is not available
Did you mean adding an audio track to a video recording? AFAIK, Audacity does not have a video component, so yes, I agree that’s not available. But
why would you use an audio editor to do dubbing? Or maybe I am misunderstanding the problem.
