FAQ do formato de arquivo MP3
MP3 (.mp3) is a ubiquitous lossy audio encoding format that balances file size and sound quality. Supported by nearly every media player, it uses bit-rate scaling and psychoacoustic compression. Use sample .mp3 files to test streaming playback, metadata (ID3) extraction, buffer handling, and cross-device compatibility.

What is the difference between CBR and VBR MP3?
CBR (constant bitrate) encodes every frame at the same rate for predictable file sizes. VBR (variable bitrate) adjusts per-frame for better quality-to-size ratio but can confuse naive duration estimators.
Why does my MP3 player report the wrong duration?
VBR MP3 files without a Xing/LAME header force players to estimate duration. Files with corrupt ID3 tags can also cause this. Use CBR fixtures or ensure VBR files include a valid Xing header.
What bitrate should I use for MP3 upload testing?
128kbps covers most consumer upload flows. Use 320kbps fixtures when testing high-quality audio pipelines or storage-tier validation. The 10MB sample here is 128kbps CBR.
