Run MagicAudioFXEditor-Setup.exe and follow the installer. The application will be installed to C:\Program Files\FruityAlfred Software\MagicAudioFXEditor.
On first launch, the Activate License dialog appears. Enter your Purchase Email and License Key (received via email after purchase). An internet connection is required for first activation.
Once activated, the license is stored locally. No internet connection is needed for subsequent launches.
To try the software before purchasing, use the trial license key MAFE-TRIAL-0000-0000 with your email address. The trial version includes all features with minor export limitations (see Batch Export for details).
Click Load Audio Files to open a file dialog. You can select multiple files at once. Supported formats:
All audio is automatically resampled to 44.1 kHz stereo on load if the source sample rate differs. Mono files are converted to stereo.
Loaded files appear in the audio track list. Each track has a checkbox for selecting it for batch processing. Use Select All to toggle all checkboxes at once.
Enable the Bypass Analysis checkbox before loading files to skip the QC analysis. This speeds up import when you don't need quality metrics immediately.
Select a track and click Remove to remove it from the list. This does not delete the file from disk.
When you select a track in the list, its waveform is displayed below the track list.
The waveform shows the full audio file with a red playhead indicating the current playback position. The played region is shown with a darker overlay. Current time and total duration are displayed at the bottom.
Click Load VST3 Plugin and browse for a .vst3 file. The plugin is added to the chain and shared across all loaded audio files.
Audio flows through plugins top-to-bottom in the plugin list. Drag and drop plugins to reorder them. This affects both live playback and batch export.
Select a plugin and click Open Plugin Editor to open its native GUI. Your favorite VST3 effects (EQ, Compressor, Limiter, etc.) work just like in your DAW.
Each plugin has a checkbox in the plugin list. Uncheck to bypass a plugin — it stays loaded but is skipped during processing.
Use Save Configuration to export your entire plugin chain (paths + bypass states) as a JSON file. Load Configuration restores a saved chain. If a plugin file has moved, you'll be prompted to locate it.
Select a track and click Play Selected to start real-time playback through the active plugin chain.
| Button | Action |
|---|---|
| Play Selected | Start playback of the selected track through the plugin chain |
| Stop | Stop playback |
Only one track can play at a time. Starting a new track automatically stops the previous one. The status label at the bottom shows which track is currently playing.
During playback, audio is processed through all active (non-bypassed) plugins in real-time at 44.1 kHz with a block size of 1024 samples. Adjust plugin parameters live and hear the changes immediately.
This is the core feature of Magic Audio FX Editor — process your entire library through a VST3 chain in one go.
| Property | Value |
|---|---|
| Format | WAV (32-bit float) |
| Sample Rate | 44.1 kHz |
| Channels | Stereo |
| Naming | (Processed)filename.wav |
| Duplicate Handling | (Processed001)filename.wav, (Processed002)... |
Batch export uses dedicated offline plugin instances, completely isolated from the live playback state. This ensures consistent results regardless of what you're doing in the UI during export.
The trial version applies the following limitations to exported audio:
| Original Duration | Limitation |
|---|---|
| Up to 30 seconds | Short silence drops (100 ms) are inserted every 3 seconds |
| Over 30 seconds | Export is truncated at 60 seconds |
Purchase a full license to remove all export limitations.
When you select a track, the QC panel displays five key audio metrics with traffic-light indicators (green / yellow / red).
| Metric | Green | Yellow | Red |
|---|---|---|---|
| True Peak (dBTP) | ≤ −1.0 | −1.0 to 0.0 | > 0.0 (clipping) |
| LUFS (Loudness) | −24 to −6 | Outside range | — |
| Crest Factor | ≥ 8 dB | 6–8 dB | < 6 dB (over-compressed) |
| Stereo Correlation | ≥ 0.0 | 0.0 to −0.2 | < −0.2 (phase issues) |
| Clipping | Clean | Near-clipping detected | Hard clipping detected |
A single status indicator summarizes all five metrics: green if all pass, yellow if any are yellow, red if any are red.
The Fix Gain button appears in the QC panel when a track's True Peak is between −3.0 and 0.0 dBTP and no hard clipping is detected.
Applies a precise gain adjustment to bring the True Peak down to −6.0 dBTP. This gives your mastering chain enough headroom to work with.
Switch between themes via View → Light Mode or View → Dark Mode.
| Theme | Background | Best For |
|---|---|---|
| Dark Mode (default) | Dark gray | Extended sessions, low-light environments |
| Light Mode | White | Bright environments, high contrast |
The main window is organized top-to-bottom:
After purchasing, you receive a license key via email. Enter it along with your purchase email on first launch. The license is tied to your machine and allows up to 2 activations (e.g. desktop + laptop).
Use the key MAFE-TRIAL-0000-0000 with your email address to activate the trial. Trial differences:
Purchase a full license from fruityalfred-software.de. Download and install the full version — the installer automatically clears the trial license. On first launch, enter your purchased license key and email to activate.
Magic Audio FX Editor checks for updates automatically on startup (full license only). You can also check manually via Help → Check for Updates.
Updates are delivered as small delta packages instead of full installers, making the download fast.
Make sure the plugin is a 64-bit VST3 format. 32-bit plugins and VST2 are not supported. Some plugins may require their own installer to be run first.
An internet connection is required for the first activation of a full license. Trial activation works offline. If the problem persists, contact [email protected].
Check that your audio output device is correctly configured in Windows. Magic Audio FX Editor uses the system default audio device. Make sure no other application is exclusively locking the audio device.
Export speed depends on the number and complexity of your VST3 plugins. Heavy plugins (e.g. Ozone, FabFilter Pro-L) require more processing time per block. There is no GPU acceleration for VST3 processing.
Make sure Bypass Analysis is unchecked. If it was checked when loading the file, re-select the track to trigger analysis. If ffmpeg is not found, LUFS measurement will use a fallback method.
Check the log file at %LOCALAPPDATA%\FruityAlfred Software\MagicAudioFXEditor\logs\ for error details. Common causes: corrupted license file (delete license.json and re-activate) or missing Visual C++ Runtime.
