    And as usual, is mucking it up.

     

    This time I got to about measure 30 or so before it all went to hell.

     

    Could some very helpful person please let me know where I went wrong so I can get back on track?

     

    Here is the project: Project

     

    Thanks.

     

    Hopefully someday I will figure this stupid thing out and can quit asking for help :sigh:

    looks like you’ve been marking BPM changes on the second beat of each measure rather than the first, which might be throwing you off. i suggest starting over from the beginning, making sure to place markers on the downbeats. for reference, the first snare hit in the song is on the second beat of the measure.

    So, let me see if I am understanding you properly. I’ve been putting my bpm markers on the second beat when I should be putting it on the first. So is it the marker at measure 4 (second measure of the actual song) that is what threw me off afterwards? That one is one beat too late? And if I start over and do that one properly, the rest should turn out better?

     

    Thanks.

    I respectfully disagree with anglebracket. Well, of course he’s right, you’re one beat off as he said but you’re off for 2 other reasons. The first one is that you’ve broken a cardinal rule: unless there is an extremely noticeable change in tempo, your BPMs should be similar for the whole song, while you chose to author the first measure at 108BPM instead of 122. Set the first BPM at 3.1.00 at 122, move the audio so that the track begins exactly at 3.1.50 (the audio itself, the first peak, not the silence before it). Now you have fixed issue #1 AND you have fixed the issue anglebracket pointed out (you will still need to go back at fix all markers before 3.1 to be 122BPMs so that your count in sounds fine).

     

    The second issue is very simple: sloppyness. <img decoding=” src=”/wp-content/uploads/invision_emoticons/default_SA_wink.gif”> Using your original file for reference, the peak at 0:51.875 should be at 28.1 (slow down the BPM marker @ 27.1) and the two measures after that drift even more, so the peak at 0:55.812 should be at M30.1.00 instead of M30.1.33. Now, keep in mind these remarks are based on your reference file, so FIRST check these to know what I’m talking about, take it on board, realign everything as I suggested and then with precise aligment of the peaks in mind proceed.

    i should have been more clear; i assumed fixing the downbeat issue would help to fix the 108BPM problem. my bad! :sweatdrop:

    I don’t think it’s so much sloppiness as me just not knowing what I’m doing <img decoding=” src=”/wp-content/uploads/invision_emoticons/default_SA_smile.gif” /> I will try what you’ve suggested and return once I have done so.

     

    Thanks.

    So I am looking at these spots right now (on my reference file)and … I don’t see peaks at these times. Certainly not the BIG peaks, which I thought were what I should be looking for. Am I doing this all wrong?

    Maybe, the peak is pretty clear to see if you put the marker where I suggested you do and there’s a 60ms long depression before that, so the peak stands out.

    Ok here is what I get when I look at that first time you point out:

     

     

    Please explain what I should be seeing as if I am little baby <img decoding=” src=”/wp-content/uploads/invision_emoticons/default_SA_smile.gif” />

     

    I can’t make customs if I cannot somehow learn to understand this fundamental, but oh so hard to grasp, concept :qq:

    That’s not your original file, you must have already realigned the audio.

    Hmm. Well I certainly don’t remember doing so… I suppose it could have happened accidentally. I will redownload my reference file and look at it again.

    So I redownloaded my original file and these points still don’t seem to line up. You said I should check that file BEFORE I move anything right?

    “move the audio so that the track begins exactly at 3.1.50 (the audio itself, the first peak, not the silence before it).”

     

     

    Also I just noticed this. Why am I placing the first peak at 3.1.50 instead of 3.1.00?

    Repost the RPP and I’ll check why it’s not aligned. You start at M3.1.50 because the song doesn’t start on a down beat.

    I see. I assume I still put markers at subsequent downbeats? This is probably what got me off track in the first place.

     

    I think I will take another whack at it now that I know this, and post a new project for review after that.

     

    Thanks for the help!
