16 bit sample format. #11

Open algabassi opened 12 years ago

algabassi commented 12 years ago

Hi,

I need to use this project to play files with others audio streams over 16 bit sample format. What is necessary to conform it?

Thanks. algabassi

Are you asking what is needed to fix Movist to play audio streams with a sample format of greater than 16 bits per sample? Or are you asking what you need to do to the audio so that Movist can play it?

I have noticed issues with audio lately. Audio with more than two channels of audio also appears to have serious issues. Movist's audio handling definitely needs some looking into.

Your first deduction is right. I need to fix Movist to play audio greater than 16 bits per sample. I'm trying to change vars from 16 bits to 32 bits, in initAudioUnit: and nextAudio: methods without success. I'm beginner in audio issues.

Ok. I'll take a look at this when I look at the multi-channel stuff.

samiamwork commented 12 years ago

Any chance you could provide me with a small sample clip with that illustrates the problem?

algabassi commented 12 years ago

of course. I'll send you by email?
