Instructions

Software Usage Instructions

Select audio files: Click the “Select audio files” area, or drag audio into the tool. Formats such as MP3, WAV, FLAC, AAC, M4A, OGG, OPUS, WMA, AIFF, and AMR are supported, and you can select multiple files at once.
Check the file list: The tool will display the names, formats, and sizes of the first 20 files. The remaining files will be indicated by a text count and will be processed together during conversion.
Set the output format: Choose a target format such as MP3, WAV, FLAC, AAC, M4A, OGG, or WebM, and set the bitrate, VBR quality, sample rate, and channels according to your needs.
Configure processing options:
- Keep audio tags: Preserve information such as title, artist, and album as much as possible.
- Volume normalization: Choose loudness normalization or dynamic normalization to make the loudness of different audio files more consistent.
- Trim time: Enter a start time, end time, or duration to extract.
- Fade in and fade out: Add smooth transitions to the beginning and end of the audio.
- Remove silent sections: Trim silence at the beginning and end based on a threshold.
Save settings: Click “Save settings” to keep frequently used parameters, which will be loaded automatically the next time you open the tool.
Start conversion: Go to the “Convert and Download” page, confirm the parameters, and click “Start conversion”.
Preview and download: After conversion is complete, you can preview the first 20 results, download files individually, or click “Download all results as ZIP” to get all converted results.

FAQ

A: Common audio input formats such as MP3, WAV, FLAC, AAC, M4A, OGG, OPUS, WMA, AIFF, and AMR are supported. Output formats include MP3, WAV, FLAC, AAC, M4A, OGG, and WebM.

A: 192kbps or 256kbps is commonly used for music, while 64kbps or 96kbps can be used for speech content. The sample rate can generally be kept the same as the original; 44.1kHz is suitable for music, and 48kHz is suitable for video dubbing or production materials.

A: WAV is usually saved as PCM audio, with a larger file size, making it suitable for editing and production. FLAC is a lossless compression format that reduces file size while maintaining audio quality, making it suitable for archiving.

A: By default, converted files keep the original file name with the target extension. If duplicate names occur, the tool adds a numeric suffix to the file name to prevent results from overwriting each other.

A: After selecting “Preserve audio tags,” the tool will try to retain metadata such as title, artist, and album. Because tag standards vary between formats, a few fields may not be migrated completely.

A: Volume normalization makes the loudness of different audio files more consistent, which is suitable for podcasts, course recordings, media collections, and similar scenarios. Loudness normalization focuses on a consistent listening experience, while dynamic normalization is suitable for recordings with large volume fluctuations.

A: Common causes include corrupted files, non-standard encoding, no audio track, overly large files, or insufficient device memory. You can try using a different source file, processing files in batches, or lowering the sample rate and bitrate before converting again.
