Adobe Audition 2021 is a powerful professional digital audio workstation (DAW) designed specifically for audio editing, mixing, restoration, and post-production. Its non-destructive editing environment, advanced audio repair tools, and seamless integration with Adobe video software make it one of the top choices for podcasters, musicians, broadcasters, and film and television post-production professionals. This article will provide an in-depth analysis of its interface, workflow, and core operation techniques.

I. Detailed Explanation of the Core Interface and Workspace

After launching Audition 2021, you will be presented with a highly customizable workspace. The default “Classic” workspace mainly includes the following core panels:

1. Editor Panel: Located in the center, this is the main area for waveform or spectral display and editing. You can perform regular editing in the “Waveform” view, or conduct frequency-based fine-tuning in the “Spectral Frequency Display” view.
2. Multitrack Editor Panel: Used for multitrack mixing projects. Here you can arrange multiple audio clips and MIDI segments, apply track effects, and perform automation control.
3. Files Panel: Usually located at the bottom left, used to manage all media files imported into the current project.
4. Effects Rack Panel: In waveform editing mode, located at the top left. Allows you to chain up to 16 effects to the current audio file and preview them in real time.
5. Markers Panel: Used to create and manage time point markers and selections for quick navigation and editing.
6. Properties Panel / Media Browser Panel: Can be switched as needed, used to view file properties or browse and import media from the local disk.
7. Levels Panel: Displays the levels meter for the main output and master bus in real time, ensuring the signal does not overload.

You can switch between different preset layouts (such as “Edit,” “Mix,” “Metadata,” etc.) via the menu bar’s “Window” > “Workspace,” or customize the layout by dragging panel borders.

II. Complete Workflow: From Creation to Export

1. Create or Open a Project

Method: After launching the software, select “New File” or “Open File” on the main screen. You can also operate via the menu bar.

• Create a New Audio File: In the menu bar, select “File” > “New” > “Audio File…”. Set the file name, sample rate (usually 44100 Hz or 48000 Hz), channels (stereo/mono), and bit depth (usually 32-bit float).
• Create a Multitrack Session: From the menu bar, select “File” > “New” > “Multitrack Session…”. Set the session name, template, location, sample rate, and other parameters.
• Open an Existing File: From the menu bar, select “File” > “Open…”, or use the shortcut Cmd + O.

2. Import and Organize Media

Location and Methods:

• Drag audio files directly into the “Files panel” or the “Editor/Multitrack Editor panel”.
• Use the menu bar “File” > “Import” > “File”, or the shortcut Cmd + I.
• Browse for files in the “Media Browser panel” and right-click to select “Import”.

Imported files will be listed in the “Files panel”, where you can create folders to manage them.

3. Edit and Process Audio

Edit a single file in the Waveform Editor:

Double-click a file in the “Files panel” and it will open in the Editor panel.

1. Basic Selection: Click and drag on the waveform to select a region. Use the shortcut Cmd + A to select all.
2. Basic Editing:
   • Cut/Copy/Paste/Delete: Use the standard shortcuts Cmd + X, Cmd + C, Cmd + V, Delete.
   • Trim: After selecting the desired region, choose “Edit” > “Trim” from the menu bar, or use the shortcut Cmd + T.
3. Apply Effects: In the “Effects Group” panel, click the effects insert, and select an effect from the drop-down menu (such as noise reduction, equalization, compression, etc.). Click the effect name to open the detailed parameter panel for adjustment.

Mixing in the Multitrack Editor:

Drag multiple audio files from the “Files panel” onto the timeline tracks of the multitrack editor.

1. Trimming and Arranging: Drag clip edges to adjust in and out points, and drag the middle of a clip to move its position.
2. Track Controls: Each track has a volume slider, pan knob, mute (M), solo (S), and record-arm (R) buttons.
3. Apply Track Effects: Click the insert in the “Effects” area on the left side of the track to add effects, or use the “Mixer” panel for more intuitive control.
4. Automation Control: Click the “Automation Mode” selector on the track (such as “Read,” “Write,” “Off”), then click the “Show Envelope” button next to the track name (such as “Volume”) to draw automation curves on the clip line.

4. Mixing and Bus Processing

• Use the “Mixer” panel to adjust the overall level balance.
• Add bus effects such as limiters and equalizers on the “Master” or total output track to ensure the final output level meets standards and audio quality is optimized.
• Throughout the entire playback process, pay close attention to the “Level Meter” panel to ensure peaks do not exceed 0 dBFS; it is recommended to leave some headroom (e.g., -1 dB).

5. Export the Final Audio

Steps:

1. In the multitrack session, make sure the green work area bar on the timeline covers the full range you want to export.
2. From the menu bar, select “File” > “Export” > “Multitrack Mixdown” > “Entire Session”.
3. In the dialog that appears, configure:
   • Format: Commonly WAV (lossless) or MP3 (lossy).
   • Location: Choose the save path.
   • Filename: Enter a name.
   • Sample Type: Make sure it matches the project settings.
4. Click “OK” to start exporting.
5. Shortcut: You can also use Cmd + Shift + E to export a multitrack mixdown.

III. Advanced Tips for Common Features

1. Spectral Frequency Display Editing: In the Waveform Editor, switch to the “Spectral Frequency Display” view. Use the “Spot Healing Brush Tool” or “Lasso Selection Tool” to select noise on the spectrogram (such as clicks or sustained hum), then press Delete to remove it intelligently—extremely effective for repairing audio blemishes.
2. Batch Processing of Effect Racks: After configuring a series of effects in an effect rack, you can click the menu in the upper-right corner of the panel and select “Save Effect Rack Preset” so you can quickly recall the same processing chain in other files.
3. Match Loudness: Select “Window” > “Match Loudness” from the menu bar. Drag the audio files you need to match into the panel, select a loudness standard (such as LUFS), and click “Run Match” to quickly make the perceived loudness of multiple audio files consistent.
4. Quick Fade Processing: In the Multitrack Editor, move the mouse to the upper-left or upper-right corner of an audio clip, and the cursor will turn into a fade icon. At this point, drag to quickly create fade-in or fade-out effects.
5. Use the “Diagnostics” Panel for Automated Repair: In the Waveform Editor, open the “Diagnostics” panel (Window > Diagnostics) to use “Delete Silence,” “DeNoise,” or “DeClicker/DeHummer” for batch automated repairs.

IV. Common Problems and Solutions

1. Problem: No sound during playback.
   • Check: Menu bar “Audition” > “Preferences” > “Audio Hardware.” Make sure “Device Type” is correct (usually Core Audio) and that the correct output device is selected.
   • Check: In the Multitrack Editor, make sure the Master output track is not muted and that the track volume fader is in a normal position.
   • Check: Whether the Mac system sound settings are normal and whether headphones or speakers are properly connected.
2. Issue: Playback stutters or produces crackling sounds after applying effects.
   • Solution: Go to the menu bar “Audition” > “Preferences” > “Audio Hardware”, and try increasing the “I/O Buffer Size” (e.g., set it to 1024 samples). This will increase latency but improve playback stability.
   • Solution: Close other applications that are consuming a large amount of CPU.
   • Solution: In the Effects Rack or track effects, temporarily disable some high-consumption effect plugins to isolate the source of the problem.
3. Issue: Unable to drag files into the Multitrack Timeline.
   • Check: Make sure the current view is in the Multitrack Editor (click the “Multitrack” tab at the top), not the Waveform Editor.
   • Check: Make sure the files being dragged are audio formats supported by Audition (such as WAV, MP3, AIFF, etc.).
4. Issue: Exported files are too quiet or too loud.
   • Solution: Before exporting, adjust the overall gain on the mixer or master track. It is recommended to use the “Normalize” or “Hard Limiter” effect during the mastering stage to control peak levels.
   • Solution: When exporting, check whether the “Normalize” option is enabled in the export settings dialog and adjust it as needed.
