A noise print is commonly used in audio mastering to help reduce the effects of unwanted noise from a piece of audio. In this case, the noise print would be a recording of the ambient noise in the room, which is then used in spectral subtraction to set multiple expanders, effectively gating out those frequencies whilst the signal level in that ...

The altered peaks and troughs of the sine wave form displayed on this oscilloscope indicate the signal has been "clipped.". Clipping is a form of waveform distortion that occurs when an amplifier is overdriven and attempts to deliver an output voltage or current beyond its maximum capability.
Adobe Audition 2 was released on January 17, 2006. With this release, Audition (which the music recording industry had once seen as a value-oriented home studio application, although it has long been used for editing by radio stations) entered the professional digital audio workstation market.

The measured dynamic range (DR) of a digital system is the ratio of the full scale signal level to the RMS noise floor. The theoretical minimum noise floor is caused by quantization noise. This is usually modeled as a uniform random fluctuation between − 1 ⁄ 2 LSB and + 1 ⁄ 2 LSB.
For example, for a 20 kHz analog audio sampled at 4× oversampling with second-order noise shaping, the dynamic range is increased by 30 dB. Therefore, a 16-bit signal sampled at 176 kHz would have a bit depth equal to a 21-bit signal sampled at 44.1 kHz without noise shaping. Noise shaping is commonly implemented with delta-sigma modulation.
In low-volume sections (where the noise would be especially noticeable) noise reduction was originally performed either by partly masking the track or, in variable area recording, narrowing the width of the transparent oscillations. Later, electronic noise reduction was used (e.g. analog Dolby A).
