It does. MP3是全损代码——没有什么东西拒绝使用它,其代价是每比AAC或Opus差质量。. That is precisely what decides whether a cut can be placed arbitrarily or has to land on a structural boundary.
修剪时有什么具体关于 MP3 的具体信息吗?

Yes — MP3框架是固定尺寸的区块,因此在框架边界上的切开土地和无缝回放标记无法在重新编码中生存. It explains most of the "the cut is a fraction of a second off" surprises.
是的:free accounts process audio up to 15 MB per file, which at typical bitrates is several hours of material; ffmpeg does the decoding and encoding, exactly as it would on a desktop。这是网站在视频之后最慷慨的上限, 音频工作很少能进入它。
