Compress MP3, AAC, and Lossless Audio on iOS & macOS
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
- Open the Audio tab in Medrea.
- Import your audio files.
- Choose your target bitrate (e.g., 128 kbps for a good balance).
- Hit Start. Medrea processes the queue locally and securely.
