In the sound files, our announcer Jennifer optionally introduces levels, frequencies, speakers and formats. In addition Make A TestTone drops markers in the files, indicating the exact frequency and amplitude at that spot.

With make a TestTone you can produce phase check sequences from stereo up to 10.2 formats. Jennifer introduces each speaker after which its phase correlation is tested against the previous speaker. All files are native to Pro Tools and all other sequencers, so they can be imported without conversions. All your connections checked in under a minute.

Here's an example of part of a 5.1 surround phase check as an mp3

Sine-wave tone generation ranges from simple test tones to precede a mix, to flexible custom level and frequency sweeps up to 192 kHz. These sweeps are used to produce totally clean sideband-free test input for quality checks on signal processing or dithering algorithms. They will brutally reveal almost every limitation, as our on-line sample rate converter comparison shows. Again Jennifer can precede each sweep by a complete spoken description.

Another example: the simplest test beep introduced by Jennifer:

(Note that these are mp3 files, accuracy has suffered from conversion to mp3)
