Audio programming and tone synthesis

Question

I am basically a business programmer, and I did nothing in the audio program with the ZX Spectrum, so I'm not sure how to ask this question correctly.

I just need some pointers in the right direction regarding writing (Android in this case, but this is really a general question) applications that deal with audio, such as a matrix of tones.

Are they based on the generation of multiple samples or are tones generated on the fly?

thank

Answer 3

Android .

One uses the AudioTrack class: http://developer.android.com/reference/android/media/AudioTrack.html

The write method allows you to output PCM data. AudioTrack can be used in streaming and static modes.

Another way is to use the Android Native Development Kit and OpenSL ES.
