The company provided worldwide on-location recording services to Telarc, Delos, RCA, Philips, Vanguard, Varèse Sarabande, Angel, Warner Brothers, CBS, Decca, Chalfont, and other labels.

[2] Although most recordings were of classical music, the range included country, rock, jazz, pop, and avant-garde.

The band recorded the album live to two-track stereo in Jack Richardson's studio, Nimbus Nine, located in Toronto, Canada.

This accounted for the "bass drum heard round the world"[7][8] review of the 1978 Telarc recording of Frederick Fennell: The Cleveland Symphonic Winds.

[5][9] Soundstream collaborated with Telarc for several years, producing legendary symphonic recordings; the earliest ones are chronicled in Renner.

Soundstream recordings made before the advent of the CD were released as high-quality vinyl LP albums.

DRC attempted to develop a home digital player that would use a photographically reproducible optical card as opposed to the mechanically pressed CD.

External hardware (tape drive, editing system, and digital delay unit) connected to the DTR through connectors on the back panel.

Another effect of the encoding process was to increase AC in the channel code to aid in clock recovery (bit sync) on playback.

The selected data were then clocked into an Analogic MP1926A Digital-to-Analog Converter (DAC) at the original crystal-controlled sample rate.

The MP201A suppresses the glitches present during the narrow segment of time that the binary input word to the DAC was transitioning from one sample to another.

Voltage and current gain sufficient for +20dBm into 150 ohms was provided by the output-buffer amplifier with the signal then output at the XLR connector on the DTR's rear panel.

Soundstream-modified Honeywell 5600e Instrumentation Tape Drives (HTD) used custom high-frequency 18-track record and playback heads.

It consisted of a Digital Equipment PDP 11/60 computer running the DAP (Digital Audio Processor) editing software (written by Soundstream employee Robert Ingebretsen), Soundstream's interface (the Digital Audio Interface) to transfer data between its recorder and the computer's disks (a pair of Braegen 14" disk drives), digital-to-analog playback hardware, a text-based video display terminal for entering commands to operate and control the DAP software, and a storage oscilloscope to display the waveforms of the audio being edited or processed.

In addition to its own facility, Soundstream installed editing systems at Paramount Pictures (Hollywood), RCA (New York), and Bertelsmann (Germany).

The sound system in the editing room in the Salt Lake facility used a Threshold SL-10 preamp, a Sumo "The Power" amp, and Infinity RS4.5 speakers.

To allow for a preview channel during the LP cutting process, Soundstream built a digital delay unit (DDU).

So that users of the Sony PCM-1610 Digital Audio Processor could take advantage of Soundstream's editing system, the company developed the S-1610 Adapter.

Essentially derived from the DTR's playback circuitry, the DAC Box was a four channel device used by the Soundstream editors to audition audio data during the editing process.
