The System

SoundCheck System: The SoundCheck®system from Listen includes everything you need to perform audio measurements on a wide range of devices – the software, the audio interface, other test interfaces and accessories, and test sequences.

Software

  • SoundCheck Software: The heart of the SoundCheck system – powerful software for all types of audio test.

Audio Testing Hardware

All-in-one hardware

  • AmpConnect ISC: USB Controlled integrated Hardware: AmpConnect ISC combines an audio interface, impedance box, amplifier, microphone power supply and digital I/O card in a single unit to simplify setup and minimize errors. This is the most cost-effective approach for most loudspeaker, headphone and microphone tests.

Audio Interfaces

  • AudioConnect: Listen’s 2-in, 2-out audio interface with a host of additional useful functionality
  • AudioConnect 4×4: Listen’s high precision 4-in, 4-out audio interface
  • Lynx: Various audio interfaces from Lynx for those who prefer an interface internal to the computer
  • RME: Alternatives to Listen Soundcards for those who require many channels.

Microphones, Power Supplies and Amplifiers

  • AmpConnect ISC: USB Controlled integrated Hardware: AmpConnect ISC combines an audio interface, impedance box, amplifier, microphone power supply and digital I/O card in a single unit to simplify setup and minimize errors. This is the most cost-effective approach for most loudspeaker, headphone and microphone tests.
  • SC Amp  Audio Test Amplifier: SC Amp is the world’s only dedicated audio test amplifier, with features such as integrated impedance measurement, fixed gain to reduce calibration errors, and DC voltage offset support. It offers low distortion and a low noise floor.
  • SoundConnect microphone power supply: SoundConnect is a single channel microphone power supply with an excellent signal to noise ratio. It powers one SCM/electret microphone and is also available with a 200V polarization option.
  • SoundConnect 2 microphone power supply: SoundConnect 2 is a TEDS compatible dual channel microphone power supply with low self-noise and a wide frequency response. It powers 2 SCM/electret or IEPE microphones or accelerometers, and is available with a 200V polarization option.
  • SCM Audio Test Microphones: SCM Measurement microphones are robust, accurate, stable, and offer excellent directional response in both near and far field. They are available in 2 lengths.

Electronic Interfaces

  • DC Connect: DC Connect enables measurement of current consumption of battery operated and other low voltage devices such as hearing aids
  • MEMS microphone Interfaces: Interfaces for measuring and characterizing MEMS (Micro-Electro-Mechanical-Systems) microphones and other devices with a 1-bit PDM (Pulse Density Modulation) output.
  • Bluetooth Interface: Interface which offers full control over all Bluetooth protocol settings and explicit control over the CODEC choice, sample rate, and transmitter power
  • Digital Audio Data Interface: A programmable serial audio data interface for a simple and direct connection between circuit board components such DSP’s, DAC’s, ADC’s, CODECS , etc. and your audio test system
