Measured & verified
The frequency certificate
Many videos promise a frequency. We measure it.
Before a track is released, we analyse the finished audio file and publish the result in the video description – target tone, tuning and stability across the whole track.
What we check
Four checks. Every track.
L / R
Target tone – is the frequency in the title really there, on the left and on the right channel?
Cent
Tuning – the reference pitch of the music, for example A = 444 Hz for 528 Hz tracks, measured in cents.
60 s
Stability – the track is split into one-minute sections, and every section must stay on target.
Clean
Clean sound – no hum, hiss or distortion, checked on the final master.
Method
Measured with FFT.
Finer than 0.05 Hz.
We analyse the final master with a resolution finer than 0.05 Hz. Only tracks that pass are published, and titles and thumbnails only name frequencies the measurement confirms. On the right: the certificate of “528 Hz Piano, Forest Stream & Birdsong”.

“Measured, not promised.”
The certificate is our own measurement of tuning and tone – not a medical or external certification. Our music is made for relaxation and wellbeing.
