Step 1: Buy Lossless

Purchase FLAC files from:

• Bandcamp (Best for independent artists)
• Qobuz (Hi-Res up to 24-bit/192kHz)
• 7digital

The MP3 Ceiling

The MPEG-1 Audio Layer III (MP3) standard defines a maximum bitrate of 320 kbps. 640 kbps songs repack

• MPEG-1 (Layer III): Max 320 kbps.
• MPEG-2 (Layer III): Lower bitrates (used for low-quality audio).

A file labeled as 640 kbps usually indicates one of two scenarios: Subject: Technical Report: Analysis of 640kbps Audio Files

1. It is not an MP3 file: It is likely AAC (Advanced Audio Coding) or OGG Vorbis. These modern codecs support higher bitrates and achieve better quality at lower sizes than MP3. High-bitrate AAC is common in streaming rips (e.g., Apple Music streams often use AAC 256 kbps, but high-fidelity rips or raw captures can exceed this).
2. It is a fake/up-scaled file: A lower quality file (e.g., 128 kbps) has been transcoded to a higher bitrate to create the illusion of quality. This results in a larger file size with no audio improvement (and potential artifacting).
3. It is a Dual Channel/Multitrack file: Occasionally, files with multiple audio streams or non-standard headers report aggregate bitrates that are higher than the standard single-stream limit.
