12/8/2023 0 Comments Waves audio trackA loud sound moves a lot of air, a quiet sound moves a little air. The "volume" or SPL (sound pressure level) of a sound is determined by the amount of air that is moved. The waveform in an audio file for speech or music or anything like that is a much more complicated compound wave composed of many interacting frequencies.Īll sound "frequencies" are simply rates of pressure change. You would set a signal generator to a particular frequency for sinusoidal waves and it would create a sine wave at that frequency. You can not, however, make a "sine wave of whatever audio file" because the file doesn't contain a sine wave.Ī sine wave is a very particular type of fixed frequency oscillation. Any DAW (digital audio workstation) or even most video editing software will display a waveform for the audio in a particular file.
