SensMe

SensMe is an automatic playlist generating system for digital music created by Sony Corporation^[1] and employed in numerous Sony branded products, including in some Walkman digital music players, the Media Go application, the PlayStation Portable, and some Sony Ericsson and Sony Xperia handsets. It uses a proprietary algorithm technology named 12 Tone Analysis which analyses audio files and then applies them to various SensMe channels based on mood and tempo of the music.^[2] SensMe is known as Random Channels (おまかせチャンネル, Omakase Channeru) in Japanese.^[3]

Method

SensMe works by using a twelve tone analysis of all the user's music individually, computing track information based on the mood and tempo of the tracks, and then outputting them for the user to play these automatically generated playlists. Initially (on Sony Ericsson devices), the software would use a dual axis map which all the analyzed tracks are plotted into,^[4] allowing the user to navigate to an area of the map to play a playlist or an individual track.^[5][6] In later devices, including Walkman DAPs and the PSP, the analyzed tracks are categorised into 12 "channels" that is navigable in a list,^[7] with names such as Lounge, Upbeat, Emotional, and others.^[8]

Compatible products

SensMe first appeared on the Sony NetJuke NAS-M90HD hard drive based stereo system which was announced in October 2006 and then released in the Japanese market.^[9] SensMe's debut on a portable device was on the Sony Ericsson W910i phone released in 2007.^[10]
