AudioFile Specifications

Audiofile Program Icon

KLZ AudioFile™ consists of three primary programs: Server, Player and Monitor. At the heart of the system is the AudioFile Server, a multi-channel audio recording engine packaged to run on a dedicated PC or “IP Appliance”. The AudioFile Server provides very reliable long-term recording of numerous audio sources and includes: silence detection, precise playback delay, Mp3 Streaming, Remote Access (web server) on all sources. A variety of audio players and a serial General Purpose Interface (GPI) make KLZ AudioFile™ ideal for many radio applications.

The KLZ AudioFile™ server continuously records multiple audio sources which can be played independently at a specific delay. All audio is recorded in linear PCM format at 48kHz sampling or at 44100. The AudioFile server in standard configuration permits delays of 1 second to 4 hours. The output is the same 48kHz/44kHz linear PCM file. The delay system can be setup in combinations of mono and stereo, and each source may have a unique delay period. Provided the server has an adequate time sync to a reliable source, delay accuracy better than 10ms can be expected for the audio, and approximately 30ms for GPIs.

Digigram - MADI

Digigram Madi Tuner Card

The PCX422e is a full featured multi channel model of the PCX series of sound cards.

Thanks to its digital and analog inputs and outputs with broadcast grade specifications, its on-board processing and unrivaled reliability, PCX422e is the reference multi channel sound card used in the radio automation systems designed by Digigram Development Partners.


Audioscience Tuner Cards

From the beginning, AudioScience has been on the leading edge of audio card technology. Its founders practically invented the broadcast radio soundcard back in the late 1980's when radio automation was in its infancy.

AudioScience today has leveraged that experience and its 15 years of existence to provide the most complete line of sound cards for both the legacy PCI and the new PCI Express buses.

MOTU Firewire/USB2

MOTU Firewire USB2 Card

Multi channel audio for your Mac or PC. Thanks to MOTU's Hybrid interface technology, the Audio Express connects to any current Mac or PC via FireWire or high-speed USB 2.0.

To fully support both formats, the Audio Express hybrid audio interface is equipped with a FireWire jack (400 Mbit/sec) and a high-speed USB 2.0 jack (480 Mbit/sec). This gives you maximum flexibility and compatibility when connecting to today’s ever-expanding universe of Mac and Windows computers.

Lexicon Alpha

A dual-input, 2-bus, 2-output USB I/O mixer with extra high-impedance instrument input and separate headphone output gives you the freedom to not only record but also mix anywhere.

 Yellowtec Puc2 

Yellowtec Puc2 USB Card

As one of PUC2’s unique features, Zero Latency Monitoring allows you to monitor your recording signal in real-time, without any delay. Choose between listening to the input signal, or the return path arriving via USB. For further monitoring convenience, an AUX output lets you connect a pair of headphones for a quick and easy audio signal check.


Echo Mia Midi Card

A unique feature of the Echo Mia-MIDI is the use of "virtual" outputs. The card appears to software as if it has eight separate outputs, which are digitally mixed down to the physical outputs using the supplied "console" software and its on-board DSP. This makes for compatibility with all popular multi-track software. And with Echo's "multi-client" drivers, more than one application, such as an editor and a software synthesizer, can be playing back at the same time.

It needs to be noted that the MIDI functions of the Mia-MIDI only work under Windows ME/2000/XP(WDM) and Mac OS X

M-Audio Delta

M-Audio Delta 1010 Card
