Many thanks for your many comments! I am really happy to have a discussion here on the Forum.
I mean that is what it is for. My reply is probably too long - sorry for this - but there were a lot of remarks.
@Maija, @heyho666, @EStudio
I am obviously very happy with your positive feedback indicating apparently that Forum software in general and AS/SuperVP/Pm2 in particular are well received by you and/or your students.
@Maija,@heyho666 - command line and tutorials: For most users command line is a show stopper - they wont even consider it. That’s why these interfaces are not teached in the IRCAM cursus and there are no tutorials. While it helps to have some understanding of the underlying signal processing algorithms, the options you find in AS dialogs are mostly one to one translations from command line parameters, so besides a more complexe presentation it is not more complexe in itself. Please don’t hesitate to pose yor questions here in the Forum. For the moment there were so few that I managed to answer all of those left handedly.
@EStudio. Many users found AudioSculpt that basically translates the command line of SuperVP into a dialog, too complexe. therefore we try to hide these … but generally we don’t drop them.
I am worried about all the compromises needed to make if fit into the commercial world, although I understand the needs for that, which would imply a substantial loss of the flexibility of the interface and a certain decrease of the quality of the sound results due to the (for the time being) exclusive usage of the real-time engine.
Concerning real time engine. This is a common misunderstanding. Together with my colleague Frederic Cornu we invested quite some time to make supervp fast, notably by means of using all the SIMD features of modern processors. I don’t deny that additionnally computers have become stronger, which certainly helps as well. So we dont rely on a real time engine in SuperVP! What you do in Max, IrcamLAB TS, on the command line, in OpenMusic (which uses command line), or in AudioSculpt, if you provide the same options you get the same result (besides rounding errors on different operation systems).It is only the interface that changes here!
There are other (non ircam) tools that favor low quality for lower cost - SuperVP (and therefore all derived products) will not do that other than letting you choose options that are faster. For example frequency domain transposition is faster but lower quality. you can select this in Max but as far as I know it is not even available in IrcamLab TS 2 !
The compromise is the other way around - you cannot run as many SuperVP objects in Max in parallel as you would like to, but we won’t compromise quality.
For friends of the command line: IrcamLAB TS2 even preserves the display of the SuperVP command line options - for the effects and the spectrogram, just click the SuperVP button, there you find the corresponding command line options. These are a litle bit different because there are
no sound files or parameter files to read, and sample rate, number of channels and so on has to be provided explicitly on the command line.
So all options are there, you find them all in the SuperVP help, but transporting a treatment from IrcamLAB TS to command line is certainly more difficult. This was a choice, on the other hand I don’t think many people ever did that.
In conclusion: there is no decrease in sound quality by design! If you have impression you have a problem with quality, then this would be a bug and you should report it!
Now flexibility: Very obviously, when it comes to signal processing and analysis and compared to AS3, there are many things missing in IrcamLAB TS2. But, I would say that the things that are already available in TS2 offer at least the same and most of the time more flexibility ! You gained “editing” (we had complaints for about 10years that this was missing), you have BPFs for all effects many of which were not available in AS3 (e.g. maxF0, sinusoidal remixing), you can tune all automation parameters (BPFs) interactively with real time feedback which was previously only possible in preview mode and only for 2 effects, there is much better multi channel support.
So I repeat, there are many parts missing, but still with respect to flexibility for me there is a considerable step forward.
Personally, I go with Maija and am curious what the developers manage to propose for the missing parts.
