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 is worth knowing before you overwrite an original you might need again.
Yes: free accounts process audio up to 200 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. That is the most generous cap on the site after video, and audio work rarely runs into it.
