Tutoriel - Configurer Audacity pour l'enregistrement
You may not need to change any of these settings as Audacity's default settings are designed to work well for you right from the start, so much so that you can probably skip-read this page.
Nothing goes 'wrong' if you attempt to record in stereo with a single microphone, though you may find that only one of the two stereo tracks has sound.
To just use the sound from the microphone:
- Go to (or on Mac) then select the Recording section, and make the following settings in the Playthrough section
-
Other tracks while recording (overdub) - Software playthrough of input
To record in the most standard way:
- In the Recording section of Preferences make the following settings:
- in the Sound Activated Recording section
- Enable
- in the Options Section
- Always record on a new track
- In the Quality section of Preferences make the following settings:
- in the Sampling section
- Default Sample Rate: 44100 Hz
- Default Sample format: 32-bit float
Project Sample Rate
- Peter 12Aug17: Updated the image - with the Project rate in context in the Selection toolbar.
The Project Sample Rate in Hz can be seen, and changed if required, in the Selection Toolbar at the bottom of the Audacity window:
The sample rate defines the number of digital audio samples per second taken from a continuous analog signal.
44100 Hz is standard for creating files that can be burned to Audio CD or for high-quality MP3 files.
This is the default setting in Audacity and is best left at that setting for your recordings.
Project Sample Format
The Project Sample Format (also known as Bit Depth or Word Size) is the number of computer bits present in each audio sample. It determines the dynamic range of the audio.
Audacity's default is set to 32-bit float. This is good for editing and processing audio. It is strongly recommended that you retain the default setting, however if you really need to change your sample format this can only be done in the Quality section of Preferences.
You can easily downsample to 16-bit (the standard for creating WAV files that can be burned to audio CD) when exporting later.
Fichiers temporaires
Le plupart des utilisateurs n'ont qu'un disque dur. Néanmoins, si vous avez plusieurs disques durs, vous voudrez vous assurez que Audacity utilise le plus grand ou celui qui est le plus rapide pour enregistrer l'audio. Ouvrez les Preferences (dans le menu Edition, ou dans le menu Audacity sur Mac) et cliquez sur l'onglet Répertoires. Assurez-vous que le répertoire affiché est bien sur votre disque dur préféré.

Si votre répertoire racine est monté sur un serveur distant, vous n'avez définitivement pas besoin que le répertoire temporaire de Audacity soit là-bas ! |
Software Playthrough
Now click on and, if you are recording from a microphone, make sure that Software Playthrough is not checked - Software Playthrough will cause undesirable feedback from the computer speakers to the microphone.
If you are recording a guitar or keyboard and want to hear the instrument through the computer speakers, make sure that Software Playthrough is checked.

Hardware playthrough:
This is a method available on some Windows and Linux machines that lets you unmute the input directly in the sound device. To use this, open the operating system sound mixer, then the Playback section, then unmute the input device (microphone or line-in) and turn the volume up. You can find the system mixer in the Control Panel at on Windows. On Linux, it may be possible to unmute input devices in ALSAmixer then set playback and recording devices in Audacity to the (hardware) device.
If hardware playthrough is required it is best to use an external USB or Firewire audio device that has a headphones jack for no-latency monitoring (such as the Behringer UCA 202 or Zoom H2). |
Overdub off
Now click on again and make sure that "Overdub (on/off)" is not checked. When this option is enabled Audacity will play other existing tracks while recording a new one. You can decide which tracks will play according to their mute/solo buttons on the Track Control Panel.
It is unlikely you will need overdub for your first recording. If you do want to overdub by (for example) singing over a recorded instrumental track, you should be aware of the Latency correction preference.
Latency correction
On most computer systems there will be a delay known as latency between singing or hitting your note and it being laid down in the recording. When is set to "on" and you record with another track already present, Audacity will push the recorded track backwards by 130 milliseconds to compensate for the delay. If your latency is constant, you can adjust the Latency correction value so that your recorded tracks should end up properly synchronized with the other tracks after correction. To set a custom latency value for your system, see the Latency Test page.
Sound Activated Recording
Also at make sure that "Sound Activated Recording" is not checked. "Off" is the default setting.
When this is enabled, recording will automatically start or resume when the recording volume rises above the chosen threshold level, and pause when the level falls below that threshold. You cannot pause Sound Activated recordings manually using the Pause button or corresponding menu item or shortcut.
Préférences dans Audacity
Si vous préférez, vous pouvez faire les paramétrages ci-dessus dans vos Preferences de Audacity. Pour y accéder, utilisez (ou sur Mac).
L'image ci-dessous montre la section enregistrement de Préférences:
Il y a beaucoup d'autres paramètres initialisables dans Préférences. Prenez quelques instants pour les explorer et les comprendre.
Par exemple, Fréquence d'échantillonnage et Format de l'échantillon peuvent être modifiés dans la section Qualité de Préférences.
