True Peak vs Sample Peak — the Clip Your Meter Can’t See
By the end: why a render can read 0.00 dBFS on every sample meter you own and still clip the converter — and the ceiling that keeps it from happening to anything we ship.
DAW AnyTools Any true-peak meterLevel Core
Sample peak is the tallest sample in the file. True peak is the tallest point of the waveform the converter rebuilds between the samples. They are not the same number — and the gap between them is exactly where masters go to clip: downstream, after you have signed off.
Step 1
Samples are dots; playback is a curve
A digital file stores dots. A converter draws the curve through them — and between two samples that both sit below zero, the curve can rise above it. Oversample a waveform 8× and you can see the real shape the listener’s hardware will play. If your meter only reads the dots, it is grading a connect-the-dots drawing by the dots.
Step 2
The measured gap
We keep a demo render in the lab for exactly this: a CONCRETE drum tops loop driven hot, the way a loudness-war export leaves the desk, then sample-normalized to exactly 0.00 dBFS. Every sample meter in the chain cleared it. The true-peak meter did not.
Step 3
The ceiling we ship to
Every file we ship — free and paid, same bar — is held to a true peak of −1.0 dBTP or lower at the pre-release gate. The margin is not wasted level. Lossy encoders (AAC, MP3) redraw the waveform again and can push peaks up on their own; the headroom is what the listener’s phone spends on the way to their ears. A master with no margin arrives pre-clipped.
Step 4
Measure it yourself
Any true-peak meter will do — most DAWs have one hiding in the metering options, and ffmpeg’s ebur128 with peak=true reads it off a render for free. If your only meter reads samples, do not guess: assume the true peak is higher than the reading and ship to the ceiling anyway. The 808 pack below prints its true peak on the product page — run your meter over the files and check us.

Common failure: paying for headroom twice
First failure: normalizing to 0.00 “because nothing clipped in the DAW” — it clips at the converter, then again at the encoder. Second failure: ceiling at −1.0 dBTP, then a “safety” limiter eating 3 more dB you already spent. Pick the ceiling, measure to it, and stop paying twice.
The number, published
Most product pages print a sample peak, or nothing at all. The free pack below prints its true peak — −1.05 dBTP — because that is the number that decides what arrives.
