A quick, direct answer
Why does source audio quality matter before vocal removal?
A quiet file is not automatically a badly compressed file. Compare recordings at similar listening levels before judging cymbal texture, unstable sound around the voice and instrument detail.
Will exporting an MP3 at 320 kbps improve separation?
Re-exporting a lower-quality file does not restore lost information. First check whether you have a genuinely better source recording.
Compare the same passages before paying for another attempt
If the instrumental sounds rough, compare the same chorus and quiet passage with the source. Determine whether the roughness existed before separation or whether bass and drums became weaker only afterwards.
Low volume and lossy compression are different
A quiet file is not automatically a badly compressed file. Compare recordings at similar listening levels before judging cymbal texture, unstable sound around the voice and instrument detail. If these problems are already audible in the source, vocal removal will not necessarily repair them. File size or bitrate alone does not establish recording quality: also consider where the audio came from and whether it has been repeatedly exported or captured from playback.
Saving MP3 as WAV does not recover lost detail
Saving an MP3 as WAV or exporting it at a higher bitrate does not restore information discarded earlier. The file may become larger without becoming a better source. If you have a genuine lossless original of the same recording, compare that instead. Otherwise, an existing MP3 can be uploaded directly. Merely renaming the extension to WAV is not a conversion and will not correct an unsupported or damaged file.
Choose an appropriate file within the upload limit
MR Maker accepts MP3, WAV, FLAC, M4A, AAC and MP4 uploads up to 50 MB. The largest file is not necessarily the cleanest recording. If your file exceeds the limit, preserve the original while preparing a compatible copy, and check that the copy plays correctly. Be deliberate about edits: trimming the recording or choosing another version may remove the introduction or ending that your rehearsal needs. Do not discard the original to make room for a test.
Compare the same passages before paying for another attempt
If the instrumental sounds rough, compare the same chorus and quiet passage with the source. Determine whether the roughness existed before separation or whether bass and drums became weaker only afterwards. Repeatedly compressing the result makes the cause harder to identify. Keep the original and the completed export, then decide which difference you want another quality setting to address before paying for another conversion. A higher processing tier cannot guarantee recovery of missing source detail.
Frequently asked questions
Will exporting an MP3 at 320 kbps improve separation?
Re-exporting a lower-quality file does not restore lost information. First check whether you have a genuinely better source recording.
Should I avoid MP3 entirely?
No. MP3 is supported. Check that your recording plays properly and sounds suitable for the intended use; resaving it as WAV is not required.
