PassMark SoundCheck is a Windows-based software tool designed to test and analyze PC sound cards, speakers, and microphones. It enables users to verify audio hardware functionality, generate test tones, and perform real-time waveform and spectrum analysis.

Key Features

Audio Hardware Testing Test and verify sound card, speaker, and microphone performance.

• Supports a wide range of audio sample rates and resolutions
• Checks playback and recording capabilities

Tone Generation Create synthetic audio test signals for analysis.

• Generates sine, square, saw tooth, spike, white noise, and pink noise
• Adjustable frequency and amplitude

Real-Time Analysis Visualize audio signals as they are recorded or played back.

• Real-time waveform display (oscilloscope-like)
• Real-time spectrum display using fast Fourier transforms (FFT)

Loopback Testing Assess distortion and fidelity by looping audio output back into input.

• Uses PassMark audio loopback cables for accurate measurement
