Thanks for all the recommendations

I will go the FFmpeg way, running it on bare ALSA for now. (And if not, it is just changing some parameters for the FFmpeg input file)

The latency of such solution does not bother me too much at this stage, but i want to address another issue :

I want the processing of the audio stream to be continuous, uninterrupted

Lets's say i can do some processing within the file read loop, but after the time interval (30 sec) i have to re run FFmpeg again. I might miss part of the audio completely, or cut it in the middle of a note which will then lead to an error in the data processing algorithm

Also, if i try to do a burst of intensive processing at some point within the interval, i might hang the file read loop and miss some data then too

I have seen an FFmpeg module on CPAN, https://metacpan.org/pod/FFmpeg Wonder if this could be of any use or better in any way vs. reading FFmpeg output through a pipe ?

For now i'm just experimenting with FFmpeg and getting output from it
