Lossless baseline for further work.
WAV preserves every detail of the source MP3, which prevents additional quality loss during subsequent edits or re-encoding. The original MP3 compression cannot be undone, but no new artifacts will be introduced.
为什么要转换
01
WAV preserves every detail of the source MP3, which prevents additional quality loss during subsequent edits or re-encoding. The original MP3 compression cannot be undone, but no new artifacts will be introduced.
02
WAV is accepted by a wider range of audio players, car stereos, and streaming services than MP3. The conversion removes a recurring compatibility friction without changing what the file actually contains.
03
WAV files are typically smaller than their MP3 counterparts, which reduces hosting, transfer, and storage costs at scale. The savings compound when serving the same content to many recipients.
