Nero SoundTrax

Chorus	Adds several slightly distorted signals to the original signal.
Convolution Reverb	Uses convolution to convert depictions of real sounds into audio signals by a computer system.
Delay	Sends out one or more delayed copies of the input signal, thereby achieving an echo-like sound.
Distortion	Distorts the signal. Frequently used for electric guitars.
Doppler	Simulates a noise source passing by and the resulting special auditory features.
Flanger	Copies the input signal and returns the copy (phase-delayed) to the original. The main difference to the similar phaser effect is the feeding back of the copied signal to the input. The feedback can be finely adjusted.
Loudness	Describes the hearing-based volume. With this effect the perceived volume can be increased without exceeding the maximum permissible amplitude.
Low Fidelity	Simulates a low sampling rate, thereby generating a lower sound quality.
Modulation	Modulates the signal with a selectable control signal. Supports amplitude modulation as well as frequency modulation.
Multi-Tap Delay	Generates individual echoes or a single reflection and describes the number of simultaneously possible echoes. This is a delay effect based on taps.
Phaser	Copies and filters the input signal with a varying band-stop filter. Then the signal is reproduced phase-ddelayed to the original signal. It is similar to the flanger effect.
Pitch Bend	Changes the pitch over the length of the audio file with the help of a speed curve. The length of the audio file can be changed or retained.
Pseudo Reverse	Creates the impression that the file is being played backwards by reversing only fragments; in reality, however, the file is being played in the correct direction.
Re-analogue	Offers several effect options by inserting interference effects, such as artificial aging through noise.
Reverb	Gives a reverb effect to the file.
Stutter	Produces a stuttering effect through cut-outs or repetitions.
Surround Expansion	Offers expanded surround sound settings. Only available if you are editing a surround audio project.
Surround Reverb	Changes the room sound. A different environment can be artificially assigned to the music file. It is possible to specify the room depth, width, height, and surface as well as other parameters.
Voice Modification	Modifies the voice in a piece of music. You can change the pitch for example.
Wah-Wah	Is primarily used to influence the sound of electric guitars. The term wah-wah approximates the sound of the induced effect.

Sample Rate

The sample rate indicates the frequency with which a signal is sampled per interval of time. It is measured in sampling values per second. The higher the sample rate the more precise the measurement, and the better the audio quality.
