how to compress 93gb speech mp3 files with low noise using lame. 2017-05-29 08:58:15 Hi I am Rupesh from India. I have a huge directory of size 93.5 gb with 8500 mp3 files and 2000 sub directories.All these mp3s are speeches recorded by someone at 64 kbps. I want to compress these files recursively using lame with 16 kbps bit rate and 11050 sample rate.I have compressed the above huge directory with above options using ffmpeg and the resulted destination directory size was 29.5 gb and the quality was not good. Then I thought instead of compressing using ffmpeg it is better to compress using lame.I have compressed some directories with options given below using lame and the quality was not good.Code: [Select] lame --abr 20 -m j -q 0 --resample 22.05 --priority 4lame --abr 16 -m j -q 0 --resample 11.025 --priority 4 lame --abr 16 -m j -q 0 --resample 22.05 --priority 4The files I converted using ffmpeg was better than the files converted using lame.In the above sound quality was not good I mean after the compression completed when I try to play these files on any music player I am getting sounds like sshhh... garrr... and some electronic noises.Please try to suggest optimal settings to compress these speech mp3 files I mean less noises like sshhh garrrr and other such electronic noises.Are there any other ways to reduce these noises during the process of compression.I think that sample rate and bit rate play a lead role together in compression I mean it is not feasible to use 44.1 kHz to 16 kbps bit rate and so suggest the correct sample rate to 16 kbps and 24 kbps.If it is not possible to eliminate these noises in 16 kbps bit rate try to suggest at other bit rates upto 24 kbps.As I am new to audio compression please suggest optimal settings I mean bitrate below 24 kbps, sample rate to the corresponding bitrate, replay gain, athtype, highpass, low pass etc., found in lame documentation.Regards,Rupesh.
