One way of stretching the length of a signal without affecting the pitch is to build a phase vocoder after Flanagan, Golden, and Portnoff.. Basic steps: compute the instantaneous frequency/amplitude relationship of the signal using the STFT, which is the discrete Fourier transform of a short, overlapping and smoothly windowed block of samples;
The loudness war (or loudness race) is a trend of increasing audio levels in recorded music, which reduces audio fidelity and—according to many critics—listener enjoyment. Increasing loudness was first reported as early as the 1940s, with respect to mastering practices for 7-inch singles . [ 1 ]
Another type of normalization is based on a measure of loudness, wherein the gain is changed to bring the average loudness to a target level. This average may be approximate, such as a simple measurement of average power (e.g. RMS), or more accurate, such as a measure that addresses human perception e.g. that defined by EBU R128 and offered by ReplayGain, Sound Check and GoldWave.
A professional audio store is a retail establishment that sells, and in many cases rents, expensive, high-end sound recording equipment (microphones, [3] audio mixers, digital audio recorders, speakers and surround sound speakers, [4] monitor speakers) and sound reinforcement system gear (e.g., speaker enclosure cabinets, stage monitor speakers, power amplifiers, subwoofer cabinets) and ...

First launched in 2003, Adobe Premiere Pro is a successor of Adobe Premiere (first launched in 1991).
While 1 atm (194 dB peak or 191 dB SPL) [11] [12] is the largest pressure variation an undistorted sound wave can have in Earth's atmosphere (i. e., if the thermodynamic properties of the air are disregarded; in reality, the sound waves become progressively non-linear starting over 150 dB), larger sound waves can be present in other atmospheres ...
Cines also received an injection of capital from a group of US investors, who built or acquired cinemas in Germany and elsewhere in mainland Europe, to increase their share of the marginal cinema revenues that Cines's films generated: [21] in 1912 the Cines company of Rome had a capital of 3.75 million lire ($712,125).
