I have used years my own Alsashmrec. It uses two processes/threads one for Alsa reading and one for disk writing. A few years ago this was absolutely necessary for skipless recording. You want this feature in the recorder you choose. Alsashmrec computes max values per a disk buffer and prints them like this: Alsashmrec 1.0 Recording format: 16-bit/44100 Hz/Stereo Buffers: A/D + Shared + Disk == 1024 + 2621440 + 163840 bytes 0000000000000000000003646564556767777677787767656856585787757678767787 7677 The print has "x" for the overflow. The screen is eventually filled with the max values. That is good because I can take a break and may still see at what point the overflow occured. Perhaps Alsashmrec should additionally print the time values at the begin of each row. When two programs are used there is danger that you monitor different signal plug than what is being recorded.
