local audio converter
The future converter will reuse the compression pipeline with preservation-oriented defaults: preserve sample rate, channels, normal loudness, and metadata unless the user chooses otherwise. Available output formats must be tested on the current browser at runtime.
Your selected file stays on this device. No upload, account, or server-side media job.
Browser-local workspace
Choose one local audio file—or a local video on the extraction route—to preview browser-readable facts and set one focused local plan. The source is not uploaded, modified, or sent to a fallback service.
No upload, account, or server-side media job.
Conversion differs from compression mainly in its defaults, not its implementation. The intended shared pipeline decodes, optionally transforms, encodes, and measures one selected file so the two tools do not drift into separate format behavior.
MP3 and WAV are planned baseline output choices. M4A/AAC and Opus/WebM should appear only when exact runtime capability checks succeed, rather than relying on a browser-name support table or an upload fallback.
Private browser handling
Aftermath reads a file you choose only in this browser tab. The shared workspace currently provides local file selection, playback, and task-specific planning; audio processing and export are not connected in this release.
