The reason behind this is clearly explained in core audio documentation (page no 51 of core audio pdf). iOS contains the recording codecs listed in Table 2-5. As you can see, neither MP3 nor AAC recording is available. This is due to the high CPU overhead, and consequent battery drain, of these formats.

Here is an example of a simple way to ‘normalize’ the audio (making it cover the whole amplitude rage but not exceeding it): audio_array *= 32767 / max ( abs ( audio_array )) And here is an example of converting it to the proper data type (note that this should always be done after normalization or other amplitude changes):
