Sox

sox is a powerful sound sample converter capable of converting between well over 20 different sound file formats. They include .8svx, .aiff, .au, .avr, .cdr, .cvs, .dat, .gsm, .hcom, .maud, .mp3, .nul, .ogg, ossdsp, .prc, .sf, .sph, .smp, .snd, .sndt, sunau, .txw, .vms, .voc, .vox, .wav, .wve, and .raw, (From sox -h) so the conversion you need should be in there. Sox can also perform some effects, such as fade-in/out, or tasks like turning up/down the volume, or resampling the audio.

= Install it = Install it by means of your distribution as described at installing Software. E.g. for SUSE Linux install it like this: yast -i sox

= Examples = sox input.wav output.ogg sox -n phaser.wav synth .5 sine 10000-5 sox -n phaser2.wav synth 0.5 sine 1600-100 \ synth 0.6 sine fmod 200-1400 mplayer phaser2.wav rec -r 22050 -c1 -p | sox -p do_i_snore.flac silence -l 1 00:00:00.1 -70d -1 00:00:00.1 -70d
 * Used in its most simple form, sox can be used to convert one audio format to another:
 * Generate a phaser sound:
 * Generate a more complex phaser sound:
 * Use mplayer to listen to your sounds:
 * Have you been told you snore or talk in your sleep? Use the 'rec' utility with silence detection to find out!:
 * The above 'rec' example will only record noise with the thresholds given. The file size stays very small (unless you snore alot), because it only keeps the noise, not the silence.
 * See the sox man page for complete details on why this works.
