Le mixage permet de superposer musique et voix, d’ajouter un fond, de créer des mixes et d’obtenir un son plus riche — localement dans votre navigateur.

Avantages

• Mix audio: Combine two tracks with independent volume control.
• Layering: Create a fuller sound by stacking sources.
• Timing control: Trim each track and delay the second track.
• Polish: Use fades, pan modes, presets, and optional normalization.
• Export options: Download as MP3, WAV, M4A, OGG, or FLAC.

This tool mixes two tracks together with adjustable volume, per-track trim, secondary delay, fades, pan, and optional loudness normalization. You can preview the mix live and export when it sounds right.

Fonctionnalités (détail)

• Waveform timeline: See primary and secondary waveforms (with delay) and scrub to any point.
• Live preview: Play and stop the mix in real time with a peak meter and clipping indicator.
• Trim per track: Set start/end for each track to cut silence or unwanted parts.
• Volume & pan: Set levels from 0–100% and choose pan modes (center or split L/R).
• Delay & fades: Delay the secondary track and apply fade-in/fade-out to the final mix.
• Normalize: Optional `dynaudnorm` to even out loudness.
• Presets: Quick starting points like voice over music, podcast mix, ambient blend, karaoke.
• Blend length: Stop at the shortest track or extend to the longest.
• Export: MP3/WAV/M4A/OGG/FLAC with bitrate and sample-rate choices (where applicable).

Processus

• Add tracks: Select a primary and a secondary audio file.
• Set mix: Adjust volume, trim, delay, fades, pan, presets, and normalization.
• Preview: Use waveform + live preview to verify timing and balance.
• Blend: Choose output settings and run the blend.
• Download: Save the blended file to your device.

Quelques points pratiques pour de meilleurs mixes.

Points clés

• Good volume balance is more important than file format for a clean mix.
• Trimming silence and aligning timing usually improves clarity.
• Normalization can help when one track varies in loudness.
• Export format affects file size; WAV/FLAC are larger than MP3/M4A/OGG.
• Very long/high-sample-rate audio can be slower to process in the browser.

Pour des résultats plus propres.

Qualité

• Start with a preset, then fine-tune volumes to avoid clipping.
• Use the peak meter; if you see clipping, lower levels or enable normalization.
• Trim intros/outros and add a short fade to avoid pops.
• If exporting lossy (MP3/M4A/OGG), avoid re-encoding multiple times.
• Prefer WAV/FLAC for editing workflows; MP3/M4A for sharing.

Cas d’usage

• Voice over music: Lower background music and keep speech clear.
• Podcast mix: Add subtle ambience and normalize for consistency.
• Karaoke: Blend a backing track with voice.
• Sound design: Layer effects and atmospheres.
• Creator workflows: Quickly mix a voice track with a beat.
