Hello, I have a few questions related to arecord, which I couldn't find in the man pages nor anywhere on the internet. My use case is very simple, I'd like to record stereo 24/192 audio into a WAV file from an E-MU 0202 USB interface using an old laptop (Core 2 Duo). For this I thought of using the device which starts with "hw:", as it seems to me that it provides the least processings over it. The recording works without problems, however I'm confused about the options. What is not clear to me: --mmap - should I use it or not? I'd be writing from USB to hard drive a wav file. --period-time, buffer-time, period-size, buffer-size - I'm totally confused about these. I'd like the highest possible recording quality, latency doesn't matter to me. --avail-min - what is a wakeup? --disable-resample/channels/format/softvol - do I need this if I selected the hw: device? I'd like to record without any kind of processing. --test-position/coef/nowait - do I need this for my use case? Thanks and regards, Zsolt _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
