1.2 About Nero WaveEditor
Nero WaveEditor allows you to record pieces of music, edit the corresponding audio files, for
example using various filters and sound enhancement methods, and finally burn them using
Nero Burning ROM or Nero Express.
With Nero WaveEditor, you edit the audio files non-destructively in real time. Thanks to an
internal reference-based audio format, the editing history is simultaneously stored so that
changes can also be undone. Various effects (e.g. chorus, delay, flanger, hall), numerous
tools (e.g. stereo processor, equalizer, noise gate), sophisticated improvement algorithms
(band extrapolation, noise suppression, declicker) as well as the filt ers and tools within Nero
WaveEditor are provided to assist you in editing your files.

Technical information
2 Technical information
2.1 System requirements
Nero WaveEditor is installed together with the full version of Nero. Its system requirements
are the same. You can find more detailed information on the system requirements in the
Nero QuickStart Guide.
In addition, the following requirements apply:
Microsoft® DirectX® 9.0b (or greater).
The latest version of DirectX® can be downloaded from the Internet under
http://www.microsoft.com/windows/directx and installed.
Minimum 5 MB free hard-disk space
16-bit Windows® compatible sound card and speakers or headphones
Installation of the latest WHQL-certified drivers is recommended. WHQL stands for
Windows Hardware Quality Labs and means that the device driver from Microsoft® is
certified compatible with Microsoft® Windows® and the relevant hardware.
2.1.1 Supported Formats
Nero WaveEditor allows you to open the following formats or to save files in these formats:
*.AC3
*.aif, .aiff
*.mp3
*.wma
*.mp4
*.ogg
*.wav, .wave
*.nwf

Terminology
3 Terminology
Sound is transmitted in air via waves. This characteristic gives rise to the following terms that
can be important for working with Nero WaveEditor:
Frequency is the number of vibrations per time unit. It is measured in Hertz.
In the case of a sound wave, the amplitude is perceived as volume (loudness). This is
the highest peak of a vibration.
Sampling rate indicates how often the sound card determines the sampling value of an
analog signal. It is measured in sampling values per second (Hertz or Hz). The higher the
sampling rate, the more precise the measurement, and the better the audio quality.
The sampling rate influences the frequency range. CDs use a sampling rate of 44,100 Hz,
in other words 44,100 sampling values per second. This means that frequencies of up to
22, 050 Hz can be recorded.
Bit depth indicates the precision with which a vibration will be captured. The higher the
bit depth, the more precise the capture, and the better the audio quality. CD's store audio
data in 16 bits. this means that each sample value can accept 65,536 possible values.

channels of a stereo file. On older recordings this is usually the voice. However, if the voice
us not distributed evenly on both channels, you can perform some fine tuning.

8.1.5 Noise Gate
The Noise Gate tools suppresses quiet sections in the signal transmission. For example, it
helps prevent noise. The Noise Gate belongs to the category of dynamic processors.
Threshold

Specifies the frequency band of the voice.
Specifies the lower frequency limit for the voice. This is typically a
value of 100 Hz.
Specifies the upper frequency limit for the voice. This is typically
a value of 7000 Hz.
Specifies the minimum dB value below which the audio file is to
be muted. In other words, the gate is closed if the dB value is too
low.
Specifies the time required to reopen the gate in milliseconds
after the threshold has been exceeded, in other words to restore
the sound of the audio file.
Specifies the time in milliseconds required to close the gate, in
other words to mute the audio file, after the level has dropped
below the threshold.
Only relevant for audio files in stereo format.
If the Linked radio button is enabled, the noise gate for both
channels is opened as soon as one or both of the two channels
exceeds the threshold.
If the Independent radio button is enabled, the noise gate closes
or opens both channels independently when the threshold is
reached.
8.1.6 Pitch Tuning
The Pitch Tuning tools changes the pitch, for example of the voice, for a short time, so that
incorrectly sung tones can be corrected.
