FLAC and Ogg Vorbis, but not generating it. Note. that by default, So. X copies input file comments to output. Replay Gain information if some was present in the input. In this case, if anything other than a simple format. Replay Gain. information is likely to be incorrect and so should be. So. X. The. soxi1 command can be used to display information. Determining. Setting The File Format. There are several mechanisms available for So. X to use to. determine or set the format characteristics of an audio. Depending on the circumstances, individual. To determine. the format of an input file, So. X will use, in order of. Command line format options. The contents of the file header. The filename extension. To set the. output file format, So. X will use, in order of precedence and. Command line format options. The filename extension. The input file format characteristics, or the closest. For all files. So. X will exit with an error if the file type cannot be. Command line format options may need to be added. Playing. Recording Audio. The play and rec commands are provided so that. These two commands are. Of course, further options and. Some systems. provide more than one type of So. X compatible audio driver. ALSA OSS, or SUNAU AO. Systems can also. If more than one audio driver has been. So. X, and the default selected by So. X when. recording or playing is not the one that is wanted, then the. AUDIODRIVER environment variable can be used to. For example on many systems set AUDIODRIVERoss. The AUDIODEV environment. AUDIODEVdevdsp. AUDIODEVhw soundwave,1,2. Note that the way of setting. SOXOPTS. below. When playing a. So.
