SoundCheck

SoundCheck 2.1 by PassMark Software is a dedicated Windows utility designed to verify the audio pipeline of any PC by generating test tones at user-selectable sample rates and simultaneously recording the output, enabling objective measurement of sound-card fidelity, speaker frequency response and microphone sensitivity. Engineers, system builders, help-desk technicians and home enthusiasts load the program to isolate hums, drop-outs or distortion without relying on subjective listening; they can loop a 1 kHz reference through line-out to line-in to confirm flat response, sweep a sub-woofer to reveal resonant peaks, or position a microphone at different angles while watching the real-time spectrum analyzer update its FFT trace. The built-in oscilloscope displays the captured waveform so that clipping, phase shift or noise floor can be quantified against the original stimulus, while automated level meters flag channels that fall outside expected amplitude ranges. Because the installer is only a few megabytes and requires no special drivers, it fits easily on a USB stick for on-site troubleshooting of conference-room PCs, gaming rigs or recording workstations. Version 2.1 remains the current release, superseding the single earlier 1.x build with tighter timing accuracy and expanded sample-rate support up to 96 kHz. As an audio diagnostic tool in the System Utilities category, SoundCheck complements PassMark’s broader hardware test suite yet stands alone for anyone who needs quick, repeatable evidence that every link in the analog and digital chain is performing within specification. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
