bulkdlExtracting audio from TikToks? That 320kbps MP3 your downloader promises is almost certainly a lie.
TikTok CDN serves audio at 128-192kbps AAC. That is the SOURCE. Any tool claiming 320kbps is just upsampling - bigger file, zero extra quality.
ABX test: could not tell 128kbps from the 320kbps output. Same data, re-encoded.
For DJs/producers: 128kbps AAC is fine for most uses. Do not waste storage on fake quality numbers.
