![]() ![]() ![]() (We add the error, since the click track is slow and falling behind.) So now, blow away the click track and generate a new one at 83.706, remembering to offset it to start on the song's first beat using the offset time noted earlier. So, instead of 83 beats per second, you need about 83.706. Multiply by 60 to convert to beats per minute: 0.706. ![]() Thus the error is 1/85 or about 0.011765 beats per second. The reciprocal of T, or 1/T, is the error in your click track.Įxample: The click track falls behind by one beat in about 85 seconds of song (measuring from the first beat). Make a note of the time difference, in seconds, between that point and the first beat. If the click track is slow or fast, find the point in the song where the click track falls behind or races ahead by a full beat. You probably do not have to use the time shift tool any more because Audacity's dialog for generating a click track lets you enter an offset (up to 30 seconds). If not, generate a faster or slower clicktrack, and time-shift it to the same starting position as before. Then, if the song really has an accurate tempo throughout, and the click track nails the exact tempo, it should stay in sync through the rest of the song. Make a not of the time shift that is required: how many seconds and milliseconds. Use Audacity's time shift tool to move the click track to begin on the first identifiable beat in the song, past its intro. have an audacity track with the song and one with a generated clicktrack and want to align the 83 bpm clicktrack with the beat of the song The underlying question, dug up from comments: ![]()
