Seppo Ingalsuo 1cbba6c5e8 EQ: Add tool for acoustical frequency response measurement ... This patch adds into SOFT/tune/eq a script mls_freq_resp.m that can be used as low budget or quick developer tool to measure device frequency response. The configuration files mls_play_config.txt and mls_rec_config.txt configure the audio devices for local or remote ssh aplay/arecord execution. The MLS measurement with a short time window, e.g. less than 10 ms can partially achieve the same as anechoic measurement. However this is not intended to replace usage any professional audio measurement. If using this use with care! Note also that as such this script measures the response of a speaker - microphone system. One response need to be known and under calibration to get reliable results for other. Even ADC and DAC responses may impact. Signed-off-by: Seppo Ingalsuo <seppo.ingalsuo@linux.intel.com>		2018-10-10 16:43:38 +03:00
