Audio recording formats
In general, the supported formats/codecs for audio recording will depend on the device and the OS version. Because of the large number of device-OS combinations that are available it is best not to select a specific format or encoder, and, instead, to use the default format/codec of the respective devices. Note the following restrictions:
•For recording to AMR-NB and AMR-WB audio formats, use only the AMR-NB and AMR-WB codecs, respectively.
•The AAC audio format can be recorded with the AAC-Low Complexity, High Efficiency-AAC, and Enhanced Low Delay-AAC codecs, but it is possible that not all of these codecs will be available or work on a given device.
