Recording a reference clip that passes first time
Reference-clip quality determines clone quality more than any other factor. This is what our quality gate checks, why, and how to satisfy it without buying anything.

Mayantar checks every reference recording before it is used. The checks are not arbitrary — each one corresponds to a specific way clones go wrong — and knowing them makes a first-attempt pass straightforward.
What gets rejected outright
Too short
A clip needs at least a few seconds of actual speech, measured after leading and trailing silence is trimmed. A ten-second file with two seconds of talking in it is a two-second clip. The model needs enough material to read your voice from; below that threshold it produces something generic and you will not know why.
Clipped or distorted
Clipping happens when the input level is too high and the waveform is cut flat at the top. It is the one problem that cannot be fixed afterwards, by us or by anyone — the information is gone. Clipped references produce harsh, brittle clones. If your recording app shows a level meter, aim for peaks around three-quarters, not pinned at the top.
Too quiet or silent
The opposite failure. A very quiet recording has to be amplified, and amplification raises the noise floor with it. Move closer to the microphone rather than turning the gain up afterwards.
Unreadable file
Corrupt uploads and formats we cannot decode. Rare, and usually fixed by re-exporting.
What produces a warning but proceeds
Mild background noise and a low signal-to-noise ratio. These degrade the clone rather than breaking it, so we tell you and let you decide. If the warning appears and you have a quieter room available, use it — the difference is audible.
How to record a clean clip with what you have
- Choose the quietest room, not the best microphone. A phone in a quiet bedroom beats a good microphone in a room with a ceiling fan.
- Turn off the fan, the AC and anything with a compressor. Steady mechanical noise is the most damaging kind because it runs under the whole clip.
- Soften the room. Recording near curtains, a bed or a bookshelf kills reflections. A bare-walled room adds an echo the clone inherits.
- Sit about a hand's width from the microphone, slightly off-axis so plosives do not hit it directly.
- Record a test, listen on headphones, then record properly. Ten seconds spent listening back saves re-cloning.
- Read the provided script at conversational speed. Do not perform, do not slow down for clarity, do not smile through it if you do not normally.
Match the reference to the work
The clone reproduces the clip, so make the clip resemble the output you want.
- Same language. A cross-language reference measurably reduces quality. Record Hinglish for Hinglish, Tamil for Tamil.
- Same microphone and room as your usual production, if you are inserting generated audio into recorded material.
- Same energy level. A calm reference cannot produce an energetic read, and an energetic reference makes calm scripts sound oversold.
When to re-record
Re-record if you changed microphones, if your first clip was rushed, if you were unwell when you recorded it, or if generated output sounds subtly unlike you and you cannot say why. It costs fifteen seconds. Each language page publishes three different scripts so you have fresh text to read.
