Audio Quantization and Free Warp
The Standard algorithm is optimized for CPU-efficient realtime processing. The
following presets are available:
Audio Quantization and Free Warp
Audio quantization and free warp allow you to edit the timing and tempo of audio
events. For that purpose the audio data is time stretched. You can choose between
different algorithms that perform the time stretching in realtime. For more information
about these algorithms, see
“About Time Stretch and Pitch Shift Algorithms” on page
102.
Audio Quantization
The Quantize function in Sequel is automatic and very useful for quickly locking drum
tracks to the project tempo.
• Load the project “Audio Quantize” found in the “Sequel Tutorial 5” folder.
This project contains a Drums event with a few timing issues.
1. Press [Space] to start playback and hear how the drum beat strays off time.
2. Activate the metronome to hear the mistakes more clearly.
3. Double-click the Drums event to view it in the Sample Editor.
4. Click the “Project Tempo” button to lock the event tempo to the project tempo.
Option Description
Standard – Drums This mode is best for percussive sounds, as it does not change the
timing of your audio. Using this option with certain tuned percussion
instruments may lead to audible artifacts. In this case, try the Mix
mode as an alternative.
Standard – Plucked Use this mode for audio with transients and a relatively stable
spectral sound character (for example, plucked instruments).
Standard – Pads Use this mode for pitched audio with slower rhythm and a stable
spectral sound character. This minimizes sound artifacts, but the
rhythmic accuracy is not preserved.
Standard – Vocals This mode is suitable for slower signals with transients and a
prominent tonal character (for example, vocals).
Standard – Mix This mode preserves the rhythm and minimizes the artifacts for
pitched material that does not meet the above criteria (that is, with a
less homogenous sound character).
Standard – Solo This mode preserves the timbre of the audio. Only use it for
monophonic material (for example, solo woodwind/brass
instruments or solo vocals, monophonic synths, or string instruments
that do not play harmonies).
