Smart Audio Compression Medrea isn't just a simple converter. It's designed to be efficient. One of its unique features is Smart Quality Protection, which prevents "fake" quality improvements that only waste space.

Professional Audio Controls

  • Bitrate Selection: From 64 kbps (Voice) to 320 kbps (High-fidelity music).
  • Sample Rate: Choose from 22.05 kHz to 48 kHz.
  • Channels: Convert Stereo to Mono for podcasts to save 50% space.
  • Lossless Support: Medrea recognizes WAV and FLAC, treating them with the care they deserve.

Smart Quality Protection

Medrea is smart enough to know that you can't "add" quality to a low-bitrate file.

  • If you try to compress a 128 kbps file with 256 kbps settings, Medrea will automatically keep it at 128 kbps to prevent unnecessary file size increase.
  • It protects against upsampling of sample rates and channels as well.

How to Use

  1. Open the Audio tab in Medrea.
  2. Import your audio files.
  3. Choose your target bitrate (e.g., 128 kbps for a good balance).
  4. Hit Start. Medrea processes the queue locally and securely.
