Online Tone Generators

Definition

Also known as a "test oscillator", "function generator" or "waveform generator", a signal generator delivers an accurately calibrated output with adjustable frequency and amplitude. Audiocheck.net provides various signal generators optimized for use in audio and acoustics applications. Those specialized signal generators are often referred as "tone generators".

The highest audio quality is guaranteed by using an uncompressed output file format with sampling frequencies up to 96kHz. Internally, our custom algorithm uses 32-bit alias-free variable-length wavetables combined with audiophile-grade interpolation. Check our benchmark.

Usage

Unlike our other sections, the output of our tone generators will be downloaded straight to your computer as a wav file. In other words, our waveform generators will generate high quality sound files, but won't play them online.

If you are looking to play audio tones straight from your web browser, please refer to our section labelled Sound Tests and Audio Test Tones.
