To Correct Audio Recording Latency

If during playback you notice your audio recordings are offset from the accompanying score, it is likely the audio signal from your microphone is not being transmitted to your computer instantly. This short delay is called latency. Finale's recording settings allow you to compensate for latency. This is a program setting and will generally only need to be set once (unless future hardware changes alter the degree of latency).

  1. From the File menu, choose New > Defaut Document. A new single-staff document appears in Studio View. We'll use this scratch document to determine the degree of latency.
  2. Click the Simple Entry Tool . Then press Enter to place a note on the first beat of the document. This is our reference point. Any note or chord is fine, as long as it rests on the first beat of the document.
  3. From the MIDI/Audio menu, choose Audio Track, then Add Audio Track. An audio track appears above the regular staff, and below the TempoTap staff.
  4. Choose the HyperScribe Tool .
  5. From the HyperScribe menu, choose Beat Source, then Playback and/or Click. Click the drop-down menu to the right of Start Signal for Recording and choose None (Record Immediately). This setting tells Finale to begin recording using the number of countoff measures specified in the Click and Countoff dialog box.
  6. Click the first measure, listen to two bars of metronome clicks, then record a marker (i.e. vocal note or percussive sound).  
  7. Click the score to stop the recording. The audio you just recorded is visible in the audio track.
  8. Click Play in the Playback Controls to listen to your document. If the audio marker you recorded and the note(s) you entered do not play simultaneously, you will need to adjust the latency.
  9. From the MIDI/Audio menu, choose Device Setup > Audio Setup. The Audio Setup dialog box appears.
  10. After Recording Latency, enter "50" milliseconds. This is a common degree of latency and a good place to start, although the exact amount of time varies by machine.
  11. Click OK. Repeat steps 6 and 7. If the recorded marker still sounds after beat one of the notated music, you will need to enter a greater duration for Latency in the Audio Setup dialog box. Repeat steps 8 and 9, entering a greater value (i.e. 65). If the recorded marker sounds before the notated music, use a lesser duration of latency (i.e. 35). Experiment with the Latency value until the recorded marker and notated music play simultaneously.
