Can I hear a difference between MP3s and uncompressed audio?

- High-bitrate MP3s (320kbit/s) are often indistinguishable from uncompressed audio, making claims of superior uncompressed audio quality questionable.
- Differences in perceived quality between compressed and uncompressed audio on streaming services may stem from processing tricks or placebo effects rather than actual audio fidelity.
- Uncompressed audio files store the original waveform digitally, while lossy compression (like MP3) removes frequencies inaudible to human ears to reduce file size.
- A personal listening test with high-quality headphones and audio interface found no discernible difference between 320kbit/s MP3s and uncompressed WAV files.
- Bluetooth headphones typically use lossy compression, meaning uncompressed audio benefits are lost unless using specific high-end codecs like aptX Lossless.
- Extreme compression (e.g., 56kbit/s MP3) introduces noticeable artifacts like metallic high frequencies, unlike transparent high-bitrate compression.
