Re: [audio] Call for an updated enhanced quicktime audio library or a small audio complementary library!
Robert I am very interested in your requests, myself repeatedly mentioned the lack of Runrev about Audio. Thatt interests me most is related functions Midi, ie to create sounds directly from RunRev for them to be played by the QuickTime synthesizer (or other ...). Unfortunately I have not the skills required to create these functions. I just did a search in Gmane (Midi / audio), the results are 1893 results for Audio and 527 for south I think many RevTalker are interested in the subject. René Robert, Je suis très intéressé par vos demandes, ayant, moi-même à de nombreuses reprises évoqué les manques de Runrev en matière d'Audio. Pour ce qui me concerne, ce qui m'intéresse le plus ce sont des fonctions liées au Midi, c'est à dire pouvoir créer des sons directement depuis RunRev pour qu'ils soient joués par le synthétiseur QuickTime (ou autre...). Je n'ai malheureusement pas non plus les compétences requises pour créer ces fonctions. Je viens de faire une recherche dans GMane (Midi/audio), les résultats sont 1893 résultats pour Audio et 527 pour Midi, je pense que beaucoup de RevTalker sont intéressés par le sujet.

You are right, in general better audio support is desperately needed. But if I understand what you are asking for, both 1 and 2 of the above can be done, if you can use player objects. To crossfade, you assign audio to each player, and set the playLoudness of one player to the opposite of the other. For example, using a scrollbar with start/end values of 0/100: on scrollbarDrag N set playLoudness of player 1 to N set playLoudness of player 2 to (100 - N) end scrollbarDrag Again, this will only work with player objects, not imported WAV files. Fade in/out is the same: simply set the playLoudness of a player to a value from 0 to 100 using a repeat loop. The bigger issue is synchronized start/stop of the players. Apologies if I misunderstood what you are trying to do.

Re: [audio] Call for an updated enhanced quicktime audio library or a small audio complementary library!
Thanks for particiapting, and... Good point...! I do not precisely remember having tried this cross fade trick. Have you? So far, i understood that the playLoudness would fix the general system loudness. So that... you could not really cross fade, but only fade in succession : fade out - from 100 to nill - fade in back from nil to 100. And this does leave a real bad hole in perception! I'll give it a go to make sure.. for the record. Again, this will only work with player objects, not imported WAV files. This implies again to make a copy of the files to the hard disk, with possible problems if user hard quits, leaving rubbish behind. But again so far the only solution it seems! The bigger issue is synchronized start/stop of the players. In my project I'm dealing with small chunks of voice recordings. So so mix'in and out is really short. I will try it that way though. ++ the idea would be to do the fade in and out just once and record the audio chunks as such, thus applying audio effects on the files, and keep them nicely in the stack, hence the call for an audio library applying effects on wave files, before playing with the player. + Ideally if runrev supported an open source compressed format we could deal with quite a lot more audio within the stacks, not relying solely on quicktime. We can always output to quicktime at the final stage, but we would need some more independant way of housing in a stack compressed audio. And this should not be too difficult as these open standards exist. AAC could be a good move, for its widespread use and on mobiles too (android), thought there may be some license requirements. http://en.wikipedia.org/wiki/Advanced_Audio_Coding We are soon going to face an interesting (!) sad situation : we're going to have better audio functions on mobile platforms than on runrev desktops time to pull the alarm trigger! -- View this message in context: http://runtime-revolution.278305.n4.nabble.com/audio-Call-for-an-updated-enhanced-quicktime-audio-library-or-a-small-audio-complementary-library-tp2216458p2216570.html Sent from the Revolution - User mailing list archive at Nabble.com. ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
Re: [audio] Call for an updated enhanced quicktime audio library or a small audio complementary library!
Ok it works... in the first attempt the audio rendering was messed up by the UI refreshing. With a little tweakering it goes fine on my old macbook! I uploaded to revOnLine the test/proof of concept stack! thanks again.
