Editing Recording Vinyl (Mac OS) (section)

=== Adobe Audition ===

==== Input/Output ====

'''Preferences''' > '''Audio Hardware...'''

* '''Device Class''': CoreAudio
* '''Default Input''': USB Audio CODEC
* '''Default Output''': Bose QuietComfort 35 ''(i.e. USB headphones)''

==== Playback through USB headphone while recording ====

This may only work with multitrack sessions, which isn't the currently documented method for recording audio in Audacity (see below).

* Create a multitrack session. 
* Pick a track and arm the recording by clicking the '''R''' button.
* Playback through headphones by clicking the '''I''' button.

==== Isolating tracks ====

* Record into a new audio file (as opposed to recording into a multitrack session track.
* The audio file will be open in a waveform editor.
* Select a track by dragging from its rough start to end and hit <kbd>M</kbd> to mark the region. A new marker will appear in the '''Markers''' panel.
* After rough markers have been placed around all the tracks, zoom in and navigate from marker to marker with <kbd>&#x2325;</kbd> + <kbd>&#x25C0;</kbd> and <kbd>&#x2325;</kbd> + <kbd>&#x25B6;</kbd>. Fine tune the marker in and out points. 
* When ready to export, select the markers in the '''Markers''' panel, right click and select '''Export Audio of Selected Range Markers'''.

===== Metadata =====

If the album, album artist, and "is part of a compilation" metadata properties are set, the tracks will be collected under a single album after being imported into the Apple Music app. Otherwise, the tracks are listed separate from each other in the app.

Metadata can be saved for audio files, but not for individual tracks defined by markers within the audio files. Album title, artist, genre can be set, but not individual track names if the tracks are subclips of the audio file. 

'''Window''' > '''Metadata''' will open the '''Metadata''' panel. Metadata will be set for the audio currently loaded in the '''Editor''' panel.

Make sure that the "track number" value doesn't contain a value. When the "title" and "track number" properties are blank, the name of the clip as displayed in the '''Editor''' and '''Markers''' panels is used for the song/track title after the song is imported into the Apple Music app. If a value is entered for "track number", the song title will be blank in the Music app.

==== Exporting tracks ====

===== Multitrack Editor =====
<div class="alert alert-warning">Use the [[#Files_panel|'''Files''']] method instead.</div>
* Stack up tracks to export in the '''Multitrack Editor'''
* '''File''' > '''Export''' > '''Multitrack Mixdown''' > '''Entire Session'''

===== Files panel =====

Alternatively, double click a file in the '''Files''' panel to open that file in the '''Editor''' panel. With focus on the '''Editor''' panel, all the regions as defined by markers in the source audio file will be displayed in the '''Markers''' panel.

* In the '''Markers''' panel, select all the tracks to export.
* '''Right click''' > '''Export audio of selected range markers'''
