You can read the file in using fread with the 'int16' option, and then write them out as a .wav file using wavwrite. (That assumes signed 16bit ints, for unsigned use 'uint16') To convert every .bin file in the current working directory to a .wav file, something like the below should work (excuse the messy code, it's not elegant, but will hopefully be effective). input_list = dir('*.bin'); for i = 1:length(input_list) fid = fopen(input_list(i).name); data = fread(fid,inf,'int16'); fclose(fid); wavwrite(data,44100,[input_list(i).name(1:length(input_list(i).name)-3),'wav ']; clear data end Sam Jelfs From: AUDITORY - Research in Auditory Perception [mailto:AUDITORY@xxxxxxxx On Behalf Of Vinay Sent: 10 August 2010 09:50 To: AUDITORY@xxxxxxxx Subject: [AUDITORY] Conversion of '*.bin' to '*.wav' extension Dear list, I have sound files in the '*.bin' extension format and I need to convert it to '*.wav' format. The files are ordinary binary files with 16 bit integer values and no file header. Any suggestions please?
