What is a music taxi?

Music Taxi has nothing to do with the means of passenger transportation, but is an audio transmission standard developed by the German company Dialog4 System Engineering GmbH. It enables studio-quality audio transmission in real time. It is used, for example, to record musicians or speakers in remote studios without having to incur travel costs and travel time. It is also often used for radio broadcasting or for live transmission at events. 
In conclusion one can say that Musiktaxi has established itself as a worldwide standard for real-time audio transmission.

Music Taxi is offered by various manufacturers as a hardware or software solution.

 

Technical details:

For good quality transmission, an ISDN line with at least 2 channels is required.
When using these codecs, the audio signal is compressed similar to the mp3 format. The MPEG-1 Layer 2 standard with 64kbps or 128kbps data rate with 48kHz sampling rate is often used. But other compression formats are also possible, but not so common.
As an alternative to the music taxi, the so-called APT-X standard was also established somewhat later as an ISDN codec. More information about APT-X can be found here.

To ensure reliable operation, a so-called "real" ISDN is required. Emulated ISDN on Voice over IP (VoIP) basis offered for normal telephone operation is not sufficient and for technical reasons does not guarantee reliable and trouble-free transmission.
In Germany, the ISDN network is currently being successively switched off and replaced by VoIP. You can now operate your ISDN devices via the router (if it has an ISDN output), but this does not work properly for real-time audio transmission.

For this reason, pure VoIP solutions are increasingly being used. In Germany at present SessionLinkPro, Source-Connect and ipDTL relatively popular (status 2018).

We are also affected by the ISDN shutdown since March 2018 and work as a VoIP solution primarily with Source Connect.
