I played with Jack , and I noticed that the default sound type is JACK_DEFAULT_AUDIO_TYPEset to “32-bit monochrome monochrome sound”.
JACK_DEFAULT_AUDIO_TYPE
I'm a bit confused: IEEE defines a 32-bit floating-point range from about 3.4E-38 to 3.4E + 38, and I was wondering what the maximum and minimum “undistorted” amplitude that jack_default_audio_sample_tcan hold this type of sound. For example, if some DSP algorithm gives me samples in the range [0,1], how can I correctly convert between them and the Jack format?
