You can record audio from a microphone or any device you can plug into the Line In port of a sound card. Before recording, you may need to adjust the input signal to optimize signal‑to‑noise levels. (See either Adjust recording levels for standard sound cards or the documentation for a professional card.)
Record audio in the Waveform Editor
Correct DC offset
Some sound cards record with a slight DC offset, in which direct current is introduced into the signal, causing the center of the waveform to be offset from the zero point (the center line in the waveform display). DC offset can cause a click or pop at the beginning and end of a file.
To measure DC offset, see Analyze amplitude.
Direct‑to‑file recording in the Multitrack Editor
In the Multitrack Editor, Adobe Audition automatically saves each recorded clip directly to a WAV file. Direct‑to‑file recording lets you quickly record and save multiple clips, providing tremendous flexibility.
Inside the session folder, you’ll find each recorded clip in the [session name]_Recorded folder. Clip file names begin with the track name, followed by the take number (for example, Track 1_003.wav).
After recording, you can edit takes to produce a polished final mix. For example, if you create multiple takes of a guitar solo, you can combine the best sections of each solo. (See Trimming and extending clips.) Or, you can use one version of the solo for a video soundtrack, and another version for an audio CD.
Record audio clips in the Multitrack Editor
In the Multitrack Editor, you can record audio on multiple tracks by overdubbing. When you overdub tracks, you listen to previously recorded tracks and play along with them to create sophisticated, layered compositions. Each recording becomes a new audio clip on a track.
- To hear hardware inputs routed through any track effects and sends, click the Monitor Input button .
Routing inputs through effects and sends requires significant processing. To reduce latency (an audible delay) that disrupts timing for performers, see Configure audio inputs and outputs.
Punch into a selected range in the Multitrack Editor
If you’re dissatisfied with a time range of a recorded clip, you can select that range and punch in a new recording, leaving the original clip intact. Though you can record into a specific range without punching in, punching in lets you hear audio immediately before and after a range; that audio provides vital context that helps you create natural transitions.
For particularly important or difficult sections, you can punch in multiple takes, and then select or edit takes to create the best performance.
Audition plays the audio preceding the selection, records for the duration of the selected range, and then resumes playback.
Punch in during playback in the Multitrack Editor
If you don’t need to punch into a specific range, you can quickly punch into a general area during playback.
Choose punch-in takes
If you punch in multiple takes, Audition layers the takes over each other in the Editor panel. To choose between takes, do the following:
To mute the original clip for the duration of the punch-in range, adjust the volume envelope. (See Automating clip settings.)
