Glitch with audio file

I'm having the most bizarre experience with this insane glitch with an audio file.

I'm trying to transcribe music for a band. They sent me the files via google drive. The way it works is, I play the files on google drive, listen to a bit, hit pause, take notation of the timecode where I paused, notate the music, scroll back a few seconds to start from the previous bar, and hit play again. It's the way I've been doing it for decades.

Today, with one of the tunes, I was doing that, and I realized that after I hit pause, and transcribed the music, when I scrolled a few seconds back and hit play again, the song was not playing where I left off. I tried this several times again, but it was definitely not playing the music where I originally hit pause.

So I tried downloading the file because I assumed this was a streaming issue. And guess what: Even with the downloaded file, the problem persists!!! Basically, if you hit pause and then scroll back a few seconds, the song is now starting from that timecode.

This makes no *********** sense. How can a downloaded file be changing the timecode at which the song starts??? What the **** is happening here?

Update: I tried again, this time opening the downloaded file on itunes (I've always been using Quicktime player), and this time the problem is not there. It seems to be a problem with Quicktime Player, as well as whatever player is the one that Google Drive uses. I guess there's one thing not to hate about itunes.

Still, what the **** is that? Why does it do that?

Just decompress the file to .wav. That will solve the problem.


(As for your question. There is no way I can be sure without having the file. But I would guess that a variable bit rate scheme that uses a newer (or much older) codec than the player is expecting could do that.)

Don't know how to fix that, but I would recommend the free download Audacity. You'll always know where in the tune you are, and you can set up loops.

Big time fan of audacity - worth the short learning curve.

But... I don't understand the issue. You hit pause, then move the play head back a few seconds, and hit play... and expect the sound file to play from where you hit pause, instead of where you moved the play head to? Or does "scroll back a few seconds" mean something other than moving the play head back?

No. The problem was that the song was, basically, starting at different timecodes. I was playing the song up to, say minute 0:10, hit pause. Then scroll back a bit before (say 0:09) and now the song was starting from the beginning at that timecode, as opposed to where it actually starts (say, minute 0:01).

I have some MP3s of old time radio shows that I used to stream to my bedroom system via a Blu-Ray player. Some files will get about 45 seconds in and then the show will start over, although the play back time continues to increase. It will loop like this continuously.

My system would otherwise freeze when that happened and it always happened to the same files. I had to hold down the power button for 5 seconds on the unit to restart it.

A lot of these old shows were recorded at very low bit rates and who knows how long ago so I attributed it to that. In other words, I agree with "This Is The End". I've had weird things happen with video files too.

QuickTime X has not been updated for three years now so I consider it abandoned by Apple. So to me it's no surprise it no longer works well.

I can't even find QuickTime X on the Apple web site anymore which is another sign that it has been abandoned by Apple.

Export the file out of iTunes as an mp3 and open it up in Quicktime and see what happens.

Ahhh... yeah, thats bizarre behavior indeed and does sound (ha!) like an issue with a codec not being interpreted correctly.
