New Soundbites from Audio Beats
Using sophisticated transient detection algorithms, Digital Performer’s Beat Detection Engine can analyze any loop or audio file and determine where the beats are in your music. You can take advantage of this powerful feature for efficient audio editing.
Using the options found in the Audio Beats menu (Audio drop-down menu -> Audio Beats), you can split a soundbite based on its beat boundaries (where DP's analysis identifies a significant transient, or audio event). Adjust the beat sensitivity and beat detection settings to enable or disable beats based on their velocity threshold, then use the "New Soundbites from Audio Beats" command to create independent soundbites.
Below is a session with a double-tracked guitar part. Invariably, there are plenty of "human" differences between the two takes. However subtle, this can cause phasing issues during playback, which can be distracting and take away from the mix. Realigning these takes is ideal, and "New Soundbites from Audio Beats" may be the easiest editing technique, based on the content of your audio files. Select both soundbites and choose "New Soundbites from Audio Beats" from the Audio menu -> Audio Beats. Next, set the sensitivity of the beats which best identifies the important transients in your audio, then click apply. Your existing soundbite is separated into new soundbites based on these beat boundaries. You can quickly tighten up the timing by moving the soundbites, or using the Slip Tool; add some short fades where appropriate.
