Hi, The default audio format when using the class SimpleSpkDetSystem (used for Android-ALIZÉ and the client/server mode) is linear PCM represented as 16-bit, signed integers. The frequency is specified in the configuration file, using SPRO_sampleRate. The endianness is assumed to be the native endianness of the current platform, but can be inverted by adding the parameter SPRO_lswap to the configuration file. The signal is assumed to be monophonic.

The README of Android-ALIZÉ has been updated with this information, and a method has been added to LIA_RAL/SimpleSpkDetSystem (and the Java version in Android-ALIZÉ) to make it easier to pass audio data when you already have it as an array of short.
