[Octave-bug-tracker] [bug #44305] audiorecorder (8000, 8, 1) returns corrupted audio stream

[Lars Kindermann]

Follow-up Comment #4, bug #44305 (project octave):

There seems to be a bug in portaudio with 8-bit formats:

https://portaudio.music.columbia.narkive.com/McNZ8eJe/pauint8-and-paint8-always-get-zero-data-in-audio-input-callback-function

But in fact there is no reason to necessarily use the different formats that
portaudio offers in Octave. They just specify the buffer format portaudio will
output the data to, regardless of the hardware settings.It is doing soby
scaling and casting if necessary- And as in Octave the data is always returned
as floats, scaled to -1..1, 8 bits can be simulated by only using the upper 8
bit of int16 before scaling.
