Tool Usage

Return to old version

Select a file or sample audio first, then set flanger parameters and start processing. Audio decoding, effect processing, and download packaging are all done on this page.

Select audio to add a flanger effect

Supports browser-decodable MP3, WAV, M4A, AAC, OGG, FLAC, and more. For batch selection, only the first 20 are shown, but all files will be processed.

Choose a preset and adjust flanger settings

The flanger effect is created by short delay, copy mixing, and periodic delay sweeping. Delay, rate, depth, and feedback shape the metallic tone, motion, and space.

Classic flanger

Base Delay4.8 ms Shorter sounds more metallic; longer adds wider comb-filter color.

Mod Depth68% Controls the delay sweep range. Higher values make the sweep stronger.

Mod Rate0.45 Hz Slow rates suit gentle motion; fast rates create tremble-like changes.

Feedback36% Positive feedback boosts resonance; negative feedback gives a different phase color.

Effect Mix52% Controls the blend of dry and processed signal.

Stereo Width62% Adds phase offset to left and right channels; mono material also gains space.

Confirm Output and Preview Range

Output defaults to WAV to preserve processed waveform quality. You can set fades, output gain, limiter protection, and preview.

Ready to Process

Output Format WAV exports directly; other formats will load local FFmpeg for transcoding.

Output Gain (dB) Fine-tune overall processed volume. Limiting reduces clipping risk.

Preview Length (sec) For quick preview of the first part of the first file.

Processing Options Limiter protection enabled

Enable soft limiter protection Peak Normalization Slight Fade In/Out

Instructions

Software Instructions

Select audio files: Click to select audio files, or drag audio into the upload area. Common formats such as MP3, WAV, M4A, AAC, OGG, and FLAC are supported, and you can select multiple files at once.
Load sample audio: If you just want to test the effect, click “Load Sample Audio” to preview parameter changes using sample material first.
Select a flanger preset: You can use presets such as Subtle Flanger, Classic Flanger, Wide Stereo, Jet Flyby, Vocal Coloration, and Guitar Texture, or adjust the parameters manually.
Adjust core parameters:
- Base delay: Controls the short delay time, affecting the metallic feel and comb-filtering color.
- Modulation depth: Controls the delay sweep range. The higher the value, the more obvious the sweeping effect.
- Modulation rate: Controls the speed of effect changes, suitable for creating slow flowing or fast trembling effects.
- Feedback amount: Enhances resonance and peak-dip changes, producing a more pronounced flanger tone.
- Effect mix: Adjusts the ratio between the original audio and the processed audio.
- Stereo width: Enhances the sense of space between the left and right channels, suitable for creating more expansive sound effects.
Confirm output settings: Select the output format, and set output gain, limiter protection, peak normalization, and slight fade-in/fade-out as needed.
Preview the effect: Click “Preview First File” to compare the original audio with a processed short segment before deciding whether to process in batches.
Start processing and download: Click “Start Processing Flanger Effect”. After processing is complete, you can download results individually or click “Download All Results (ZIP)” to get a compressed package.

FAQ

A: The audio flanger effect, also called the Flanger effect, mixes the original audio with a short-delayed, continuously changing copy to create comb filtering and a sweeping feel. It is commonly used for vocals, guitars, synthesizers, soundtracks, and creative sound effects.

A: Delay determines the basic tone of the flanger, depth determines the delay sweep range, and rate determines the speed of the sweep changes. In general, shorter delays sound more metallic, higher depth makes the effect more obvious, and lower rates are suitable for naturally flowing sounds.

A: Feedback intensity increases resonance and peak/dip variation. For vocals and narration, lower feedback is recommended; for instruments and special sound effects, you can increase it appropriately. Excessive feedback may make the sound sharp, so it is recommended to preview it before batch processing.

A: Result files will keep the original file names as much as possible, only replacing the extension with the selected output format. If duplicate names are encountered, a number will be automatically appended to the file name to avoid overwriting each other.

A: No. Audio decoding, effect processing, format export, and ZIP packaging are all completed on the current page, and files will not be uploaded to the server.

A: Common reasons include corrupted files, format encodings that cannot be decoded in the current environment, insufficient memory due to files being too large, or failure to load the transcoding component. You can try using WAV or MP3 files, reducing the number of files processed at once, or testing parameters with a shorter audio file first.
