True peak: perché i dBTP contano nel mastering

Definition

Samples are discrete; reconstruction peaks higher than any sample.

dBTP reports that maximum.

dBFS sample peak is not enough for streaming.

LUFS and dBTP are independent.

Limiting at 0 dBFS sample peak may still overshoot dBTP.

Verified meters on Plugg Supply repeat safe exports.

Teach collaborators dBTP on stem handoffs.

Same rules for beats and albums.

Fixed oversampling when comparing bounces.

Screenshot meter with master version.

EBU R128 and ATSC standards reference true peak for broadcast; streaming adopted similar caution for consumer encode chains.

Headroom for vinyl cut is separate topic; digital streaming masters focus on dBTP and LUFS pairing.

Inter-sample peaks can rise when upsampling during mastering—always measure at final sample rate of export.

Dither noise raises noise floor but does not create true peak overs; confusion between the two causes wrong fixes.

Some limiters show GR while true peak still exceeds ceiling—trust dBTP meter not only GR amount.

Clipper plugins crush sample peaks but may leave inter-sample risk if not true-peak aware.

Apple Music Sound Check and Spotify loudness normalization do not replace need for clean true peak on upload file.

Distortion from true peak clipping can sound like harsh sibilance on vocals after encode—fix source not EQ after.

Mastering for SoundCloud pre-normalization still benefits from true peak discipline when same file goes to distributor.

Two-pass offline limiter renders sometimes differ slightly from realtime—verify offline bounce.

Educational meters teach difference between peak, RMS, LUFS, and true peak—learn all four readouts.

Receiver headphones with built-in DSP can hide clipping that phones on flat playback reveal.

Collaborators asking for ‘no limiter’ stems mean you should still avoid true peak clip on each stem.

Plugg Supply limiter and meter pairings in verified set help consistent home mastering chain.

Archive pre-master without limiter for future remaster when better true-peak tools release.

Producers revisiting this workflow in FL Studio and Ableton should save presets and document BPM, key, and plugin order for the next session. Plugg Supply lists verified tools via Telegram after file verification.

Streaming

Lossy codecs worsen clipped sources.

Many distributors want ≤ −1 dBTP.

Normalization does not fix baked clipping.

Bass-heavy genres raise inter-sample risk.

vs Sample Peak

−0.1 dBFS can be +0.5 dBTP.

Use ISP or true-peak limiters.

Workflow

Meter loudest eight bars.

Lower ceiling not makeup if over.

Compare after encode when possible.

FL Studio

Limiter ceiling plus dBTP meter VST.

Wave Candy is sample peak only.

Verify in Edison after export.

Ableton

Limiter ceiling; third-party dBTP meter.

Re-import master for QC.

Plugg Supply

Verified dBTP meters via Telegram.

Document export preset.

Pair with streaming export guide.

Myths

−14 LUFS alone does not prevent clips.

16-bit does not fix overs.

Home uploads same rules as majors.
