// Core Features
Engineered for the Maximum.
320kbps CBR

Fixed Constant Bitrate ensures maximum fidelity and compatibility with professional audio hardware, radio systems, and broadcasting.

🔁
Batch Processing

Drop multiple files at once. The engine queues and converts them all — WAV, AIFF, FLAC, ALAC, OGG, WMA, AAC, and MP3.

🧵
Multithreaded

Conversion runs on a separate thread. The UI stays responsive even when FFmpeg is processing at 100% CPU capacity.

🏷
ID3v1 Tag Editor

Apply metadata in bulk: Title, Artist, Album, Year, Genre, and Comment — directly embedded into every output file.

🎯
Precise Progress

FFmpeg pre-reads each file to extract exact duration in seconds, calculating a real-time accurate progress bar per conversion.

🆓
Free Software

320 MP3 Fast Encoder is completely free. No subscriptions, no ads, no hidden limits. Pure encoding utility.

Interface & Navigation

Tag Editing — ID3v1 Editor

Clicking the edit icon opens a side panel where you can set: Title, Artist, Album, Year, Genre, and Comment.

Important: All fields defined in the editor will be applied to all files in the current queue after clicking APPLY.

Conflict Management

When an output file already exists in the destination folder, a dialog presents three options:

  1. Overwrite — Replaces the existing file.
  2. Keep Both — Renames the new file (e.g. song_1.mp3).
  3. Skip — Skips conversion for that specific file.

Workflow Algorithm

  1. Ingestion — Paths received via Drag & Drop are normalized by the app.
  2. Metadata Mapping — If tags are set, -metadata flags are generated for the FFmpeg command.
  3. Duration Analysis — FFmpeg pre-reads each file to obtain exact duration in seconds for the progress bar.
  4. Transcoding — Input decoded in real time; psychoacoustic modeling removes inaudible frequencies; data written to disk at 320kbps CBR.
