The software will be a command line utility which records from audio input and directly writes into a compressed audio file. It also waits with the recording until it detects the first sounds and stops after a longer break. This allows for unattended audio tape transfers.
I have written this once in C++ with the alsa and lame libraries.
I am going to rewrite it now in python to learn python and because the old version doesn't work with newer alsa versions.
