Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.
I am developing an app where the user can record their voice, and then alter it in some way. I have implemented OpenAL, and I am able to adjust the pitch to speed up and slow down the audio file. The thing is, I want to add filters like echo, reverb, etc.. I have scoured the internet for hours and have found nothing to help me. I came across a OpenAL called FreeSL, which has a bunch of filters built in, but I cannot get it compile in xcode.
I have also looked into Dirac3, but again all I am seeing is basic pitch/time controls; no echos or anything.
Can anyone point me in the direction a good framework or explain how OpenAL can handle filters like this?
but audio processing is not something easy, it is a huge topik.
I understand now that it is not easy hah. Well I had looked at both of those examples earlier and none really help my current issue, which is adding filters and effects to audio.

yes, and to do that you need access to raw audio data (low level) applying some alghoritm to data, so there is not an [sound applyFunVoice]; function to call :D

I understand that; but all OpenAL gives you access to is simple things like gain, pitch, and velocity; would any effects I want to create be created using just them?
