Audio equalizer guide
サポートされているオーディオ形式
Add common music, recording, and voice-note formats. A file can be opened when its codec is supported by your current browser; the file extension alone does not guarantee that.
WAV / AIFF
Uncompressed audio for editing, interviews, and recording archives.
M4A / AAC
Efficient audio often made by phones, Apple devices, and recorders.
FLAC / OGG / Opus
Lossless or web-friendly formats for music libraries and speech workflows.
How to equalize audio online
No account, installation, or upload is required. Listen to the same local file while you adjust the settings.
- 01
音声ファイルを追加する
Drop in a file or select one from your computer or phone. The waveform and basic level data are read locally.
- 02
プリセットを選択する
Use Bass Boost for more weight, Treble Boost for more detail, or Voice Enhance to reduce rumble and bring dialogue forward.
- 03
Adjust and A/B preview
Start with Balanced, then switch between Original and EQ preview while playback continues. Keep boosts modest when the source is already loud.
- 04
Export the result
Choose MP3, M4A, WAV, or FLAC. The optional smooth ceiling helps prevent harsh clipping after boosts.
Common equalizer use cases
Equalization shapes tonal balance; it does not reconstruct detail that was never recorded or fully repair severe distortion.
Podcasts, meetings, and interviews
Use Voice Enhance to cut low rumble and make spoken words easier to hear on a phone or laptop.
Music and DJ demos
Add restrained low-end weight to a thin track, or add high-frequency detail to a dull recording.
ビデオナレーションとコース
Give narration more presence before adding it to a video or sharing a lesson recording.
Voice messages and field recordings
Make a quick mobile recording more intelligible before sending or archiving it.
Private by design: files stay on your device
MediaBunny decodes and exports audio in a dedicated Web Worker in this browser. The source file is not uploaded to MediaKit servers or copied to cloud storage. Removing the file, cancelling a task, or closing the page releases local browser resources.
FAQ
Audio equalizer FAQ
私の音声ファイルはアップロードされていますか?
No. Analysis, live preview, and export happen locally in your browser.
Why does the preview differ slightly from the downloaded file?
The live preview uses your browser’s audio engine for instant A/B switching. The export uses the same filter settings in the MediaBunny Worker and then encodes the chosen output format, so lossy MP3 or M4A encoding can add a small difference.
Which preset should I use for speech?
Start with Voice Enhance at Balanced. It applies a high-pass filter around 90 Hz and boosts presence around 2.2 kHz. Lower the intensity if the voice becomes too sharp.
What does Prevent harsh clipping do?
A boost can push samples above the digital maximum. This setting applies a smooth ceiling only near that limit, avoiding the abrupt crackle made by hard clipping.
どの出力形式を選択すればよいですか?
Use MP3 for the broadest compatibility, M4A for efficient AAC sharing, WAV for uncompressed editing, and FLAC for lossless archiving.
Can I process a long recording?
Yes, up to 500 MB. Keep the tab open, close memory-heavy apps or tabs, and use a recent browser for best results.
