Audio Unit recording: increased volume of buffers
===

I am building an audio recording app for iPhone in which I use remote audio units. After performing some audio analysis on incoming buffers I write the buffers to disk using:

ExtAudioFileWriteAsync

However, the problem I have is that the recorded buffers are quieter than I would like.

I would like to increase the volume of the buffers by manually multiplying them by a volume factor just prior to writing to disk. Can anyone please explain to me the best way to do this?

(For various reasons, a manual adjustment at the final stage is more attractive than changing any of the audio unit properties, which otherwise work well for my application.)

Thanks in advance!!
