# Record a good sample for cloning

How to record a clean sample for an Instant or Professional voice clone, covering where to record, how to speak, how long to record and which files work.

A clone copies what it hears. A clean sample gives a clean voice. A noisy or
mixed sample gives a noisy or mixed voice. This page is the short list of
what to do before and while you record, for an Instant clone and for a
Professional voice.

## Before you record

- Use your own voice only. One speaker, no one talking in the background.
- Pick a quiet room. Close windows and doors. Turn off fans and music.
- Avoid echo. A room with a rug, curtains or a sofa sounds better than an
  empty hall or a bathroom.
- Pick the **Dialect** you will use the voice in. Speak in that dialect.
- Check the browser may use your microphone.

## While you record

- Keep one steady distance from the microphone for the whole recording.
- Speak at a natural pace, as you would in a normal talk. Do not whisper or
  shout.
- Read the whole line the page shows. Do not stop in the middle.
- If you make a mistake or a loud noise happens, press **Remove** and record
  again. A short clean take beats a long noisy one.

### Instant

Press **Record** and read the line under **Read this out loud**. Keep going
for 10 to 30 seconds. The page counts for you:

- **Keep reading: N more seconds** until you reach 10 seconds.
- **Good. You can stop now, or keep going up to 30 seconds** from 10 seconds on.

A recording stops by itself at 30 seconds. A clip over 30 seconds is refused,
not trimmed. The step is on [Clone your voice](/docs/playground/clone-your-voice).

## For a professional voice

- Upload 10 minutes to 3 hours. Training needs at least 20 minutes of clear
  speech after cleanup, so aim for 30 minutes or more.
- Use varied speech: different sentences, questions, numbers and a few
  longer passages. Do not read one sentence again and again.
- Keep the same voice, the same microphone and the same room in every file.
- Use short files. Up to 20 files, 2 GB in total. A recording in the browser
  stops at 30 minutes, so record in parts.
- Leave out long silences, music and other speakers. They do not count as
  clear speech.

The steps are on [Train a professional voice](/docs/playground/train-a-professional-voice).

## Files that work

| Mode         | Files                                                                                              |
| ------------ | -------------------------------------------------------------------------------------------------- |
| Instant      | One file of any audio the browser can open. The page converts it. WAV, MP3 or M4A are safe choices |
| Professional | Up to 20 files, 2 GB in total: WAV, FLAC, MP3, M4A, AAC, OGG, OPUS or WEBM                         |

If the page cannot read an Instant file it says **This file could not be read.
Try a WAV, MP3 or M4A file.**
