Using the av bars tone studio

Seven equal-width bars show white, yellow, cyan, green, magenta, red and blue. These are full-channel RGB fills, not calibrated broadcast bars. The tone is a mono 48 kHz PCM WAV with a short fade at each end.

A worked example

The default produces a 1280 × 720 PNG and a one-second 1,000 Hz tone at 0.1 peak amplitude. Both artifacts are generated locally.

Before you use the result

Not a calibrated SMPTE pattern, loudness reference or measurement of a display or speaker. Device volume changes playback level; start low. The tone file is synthesized, not a recording.
