The SoX command line program lists 85 sound formats. I need one that converts WAV files to a text format, listing the amplitude values in numerical form, preferably as integers.
Which format does that?
The Windows program GoldWave has the text format that does exactly that, but I need one that can be used in batch.
I think you want ".dat".
From the soxformat man page for Linux:
.dat Text Data files. These files con‐ tain a textual representation of the sample data. There is one line at the beginning that contains the sam‐ ple rate, and one line that contains the number of channels. Subsequent lines contain two or more numeric data intems: the time since the beginning of the first sample and the sample value for each channel. Values are normalized so that the maximum and minimum are 1 and -1. This file format can be used to cre‐ ate data files for external programs such as FFT analysers or graph rou‐ tines. SoX can also convert a file in this format back into one of the other file formats. Example containing only 2 stereo samples of silence: ; Sample Rate 8012 ; Channels 2 0 0 0 0.00012481278 0 0
