We are close to finishing our current production and there is this one song that just seems a little too slow with the final arrangement and instrumentation (3% speed-up would do the trick). Now, time stretching is obviously readily available in a lot of software solutions, however, the ones that I have used on complete mixes so far result in unacceptable loss of quality. Time stretching/compressing individual tracks gives somewhat improved results, but still the overall loss is something that I will not tolerate. Short of re-recording the entire project, do professional mastering facilities usually offer top-quality time stretching/compressing services that will meet my quality expectations? Thanks in advance, MisterBlue.
