Audio Effects
These effects can be applied into audio tracks or audio parts via the Audio Editor or via the Audio Menu. If you use the menu, you must select the track and parts you want to be modified. If the part button (in the Track Manager) is enabled, the functions operate on selected parts. If not, the functions operate on selected track ranges.
If you have selected more than one part/track and you have a multicore CPU, then TP applies all audio effects simultaneously, taking full advantage of your CPU cores.
All audio effects are subject to undo/redo and non destructive editing.
Almost all audio effects (but from a few exceptions) allow you to save or load presets, either per project or globally.
Turbo Play also defines effects that are applied to more than 1 ranges (channels or parts). These effects do not use all CPU cores because they have to process all the selected ranges simultaneously. Because these effects must process the ranges simultaneously, they can be only applied in the non-part mode (because the ranges of all applied channels must be the same).

Note: Single-Channel effects can still be applied to more than one ranges. The difference between these and the multiple-channel effects is that the single-channel effects output the same result for each range, whereas the multiple-channel effects produce different outputs when they are applied to single or multiple channels. For example, the "Reverb" delay effect when applied to 2 channels produces different result than when the "Stereo Reverb" delay effect is applied to the same 2 channels.

Currently TP supports these audio effects:
Basic Effects
These are the basic effects.
- Mute
This mutes the selection
- Reverse
This reverses the selection.
- Invert
This inverts the selection (changes all samples to their opposite values).
- Sample Editor
This allows you to edit samples by hand.
Amplification Effects
These effects manipulate the volume level of the sound.
- Amplification
Allows you to change the signal's volume. Parameters are:
- Amplification percentage (0-200%) shows how to amplify. Specifying 100% leaves the signal unchanged.
- Declipper (on/off), if on, the amplification is checked for clipping and clipping is removed.
- Fade
Changes the volume from a position to a position. Parameters are:
- From percentage, specifying the starting amplitude
- To percentage, specifying the ending amplitude.
For example, a "fade in" preset could be From 0% To 100%
- Declipper (on/off), if on, the amplification is checked for clipping and clipping is removed.
- Envelope
Enveloping presents you a drawing tool which you can design a linear or bezier curve for amplification (for more, see Automation Curves)
- Normalize
Normalizes the selection to a maximum value.
- Declipper
Standalone declipper
Delay Effects
These effects present or manipulate delays in the signal.
- Delay
The simplest delay with samples number configuration
- Echo
Supports decay/delay/gain values and declipper
- Chorus
Chorus effect with decay/delay/gain/speed/depth/modulation parameters.
Reverb Effects
These effects generate reverb.
- Reverb
Standard reverb with room size and damp/width/wet/dry parameters.
Modulation Effects
These effects modulate the signal.
- Chorus
Chorus effect with decay/delay/gain/speed/depth/modulation parameters.
- Pitch Shift
Changes the pitch of the signal.
Dynamics Effects
These effects manipulate the signal's dynamics.
- Compressor
Standard compressor/limiter.
Generate Effects
These effects generate sound.
- Noise Generator (White/Pink/Brown)
This presents a dialog box which allows you to generate noise.
It allows you to generate 3 types of noise (White,Pink or Brown), replace existing data or mix with existing data, and also set the noise's intensity (0-100).
- Tone Generator
Allows you to generate sine waves.
Stretch Effects
These effects stretch the pitch or the time.
- Pitch Shift
This presents a dialog box which allows you to shift the pitch from 50% to 200%.
- Time Stretch
Allows you to stretch the time (without changing the pitch) from 50% to 200%.
- Resample
Allows you to resample a track.
Filter/EQ Effects
These effects apply a filter or equalizer to the signal.
- Non Recursive Filters
Allow NRFs (FIRs) Low/High/BP/BS and specific order to be applied to the signal.
- Recursive Filters
Allows IIRs of the following algorithms to be generated and applied:
- Bessel
- Butterworth
- Chebyshev I
- Chebyshev II
- Elliptic
- Equalizer
Equalizer as a standalone effect, see Equalizer.
Restoration Effects
These effects restore the signal from errors.
- Noise Reduction
Noise reduction works in a 2-step process:
- First select one part or one range that has nothing but the noise you want to remove, then select "Get Profile"
- Then select the parts/regions you want to process and select "Noise Reduction". The known recorded noise profile will be updated.
You are also able to choose the percentage of reduction, and whether to keep the noise or not. The effectiveness of this algorithm depend on the type and amplitude of the signal, the type and amplitude of the noise, your profiled section etc.
VST Effects
These effects apply VST plugins to the signal.
Miscellaneous Effects
Various other effects
- EarWax
A filter for desharpening 44100Hz samples.
MuiltiChannel Effects
These effects process more than one channel simultaneously.
- Pan
- Mixer
- Rotation
- Stereo Reverb
Each of the effect can also be applied as a take (for more on takes, see Track Manager)
Non destructive audio editing is supported if the effect can be reversed. For example, you can first invert the sample then filter it. Then you can only undo the invert (and the filtering will be reapplied).
