In [[telecommunication]], '''transcoding''' is the direct [[digital]]-to-digital conversion from one encoding scheme, such as voice LPC-10, to a different encoding scheme without returning the signals to analog form.

Encoding into a lossy compression format will strip details from the file. Transcoding from one lossy compression format to another will compound the loss of details from the file. (eg: transcoding a sound file from [[OGG Vorbis]] to [[MP3]]). The preferred method is to save all audio content "masters" isin a lossless audio format such as [[FLAC]] or [[WavPack]], and then transcode directly from the lossless source to your preferred lossy format such as [[MP3]]. This procedure preserves as much of the original audio signal as possible without introducing distortion and prevents compund loss of details from the file.

<i>Note:</i> The transcoded signals, <i>i.e.,</i> the digital representations of analog signals may be any digital representation of any [[analog signal]], such as voice, [[facsimile]], or quasi-analog signals.
