1.2About 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 filters and tools within Nero WaveEditor are provided to assist you in editing your files.

2 Technical information

2.1System 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).

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.
