Check box
Use dithering when converting to lower bit depths
|
Overlays sound errors that arise when converting to a lower bit depth with a white noise that is hardly noticed by human hearing. If there is no dithering, clearly audible interference can be heard when converting to lower bit depths.

Drop-down menu
Noise shaping filter
|
Specifies the type of noise shaping.
IIR filter (2nd order): Infinite Duration Impulse Response. Uses IIR filter. IIR filters can provide an infinitely long and continuous impulse response. In general they achieve a better subjective audio quality than FIR filters do, however they have higher levels of interference energy outside of the audible range. 2nd order means that sound is attenuated by 12 dB.
FIR filter (3 taps): Finite Impulse Response filter. Uses FIR filters. FIR filters possess a pulse response with guaranteed finite length. This entry is selected by default.

Restore wave output volume when closing Nero WaveEditor
|
Restores the volume of the audio file when Nero WaveEditor is closed.

Drop-down menu
Bit depth during playback
|
Specifies the bit depth during the playback of the loaded audio file.

Drop-down menu
Play surround audio as
|
Specifies how surround audio is played.
Multichannel audio: Plays back surround audio with all channels.
Stereo using Nero HeadPhone (Virtual Surround): Plays back surround audio filtered down as stereo, with a virtual surround effect generated for headphones.
Stereo with Nero VirtualSpeakers (virtual surround): Plays surround audio filtered down as stereo, whereby a virtual sound effect is generated for speakers.

| IIR Filter |
A filter is a system that links an input signal with a transmission function and makes this changed signal available at its output. A filter with infinite pulse response (IIR filter) uses the input values as well as buffered values of the output signal.
| Bit Depth |
Bit depth indicates the precision with which an oscillation vibration will be captured. The greater the value, the more accurate is the acquisition and the better is the audio quality.
| FIR Filter |
A filter is a system that links an input signal with a transmission function and makes this changed signal available at its output. With a filter with finite pulse response (FIR filter) the output signal is made up of several partially buffered values of the input signal.
