Hi,
I have some voice prompts in WAV format (PCM, 44KHz, 16bit, mono, bitrate 705kbps) and I want to convert them in gsm format. Using : sox file.wav file.gsm The result is a gsm sound file which when is played the speed is very very low (something like 5-6 times slower). Converting first to a 8KHz, 8bit mono wave file, the final gsm file is correct, but the quality is far than acceptable. The original file is at a very high quality.
Which is the procedure to obtain the highest quality possible from my original wav file?
Thanks, Dan
Sox can convert the bitrate and the format at the same time, which in my experience produces pretty good results.
I posted the process that I use to the list a few weeks ago:
