Hi all: is there a way to further improvise this audio recording script ?
#!/bin/sh arecord -D hw:0 -f S16_LE -r 44100 -c 2 > output.wav There are few queries that i have: 1. for a 20 sec audio, the generated file is 3.5+ Mb should the sampling rate be reduced or some compression utility be piped ? 2. a 'kir-kir-kir' sound also recorded when the laptop is running on power through UPS. however no such sound comes when power cable is disconnected. What are the good approaches to filter such sounds ? All suggestions and replies are welcome. thanks Saifi.
