Dialogic ADPCM

Dialogic ADPCM or VOX is an audio file format, optimized for storing digitized voice data at a low sampling rate. VOX files are most commonly found in telephony applications, as well as an occasional arcade redemption game. It uses a lossy compression algorithm, optimized for voice, not high fidelity.

Similar to other ADPCM (Adaptive Differential Pulse Code Modulation) formats, Dialogic ADPCM compresses audio data into a series of 4-bit samples. The original Dialogic ADPCM paper (linked to below) does not specify or mention a recording or playback frequency; it may be at the implementer discretion. However, traditionally, files commonly have a sampling rate of 6000 or 8000 samples per second, but 8000 samples per second (8000 Hz) is more common. 8000 Hz matches the sampling rate used in G.711 voice systems such as DS1.

Unlike a WAV file, a VOX file does not contain a header to specify the encoding format or the sampling rate, so this information must be known in order to play the file. If not known, it is normally assumed that a VOX file is encoded with Dialogic ADPCM at a sampling rate of 8000 Hz. It is possible that a VOX file may be encoded in a format other than Dialogic ADPCM, but this is not common.

Vox (song)

"Vox" is the debut single by Canadian singer-songwriter Sarah McLachlan. It was released in 1988 in Canada from her album Touch, and as a CD-single in 1992. The 1989 Arista Records release of Touch contained a different mix of the song from the original 1988 album, and different extended remixes were released as well.

"Vox" was also featured on McLachlan's 2005 Bloom: Remix Album as a contemporary dance remix by Tom Middleton.

Vox (Spanish political party)

Vox (often stylized as VOX) is a political party in Spain founded on 13 December 2013 by former members of the People's Party (PP).

History

It was founded on 17 December 2013, and publicly launched at a press conference in Madrid on 16 January 2014. The reasons for this schism seem to be the way the incumbent PP government dealt with the issue of the violence of separatist group ETA, the fiscal policy of the PP and the desire for a more centralized government in contrast to the current, quasi-federal political system ("State of Autonomies") instituted in 1978. Vox opposes Basque and Catalan separatism in general. VOX have labelled themselves as a right-wing and Christian democratic party. The first provisional chairman was the philosopher José Luis González Quirós (provisional until the party's internal election in late 2014). Other members are Santiago Abascal, Iván Espinosa de los Monteros and José Antonio Ortega Lara (well known for having been kidnapped by ETA for more than a year).
