Systems and methods for dynamic audio processing

摘要

Systems and methods presented herein may provide for processing audio with increased loudness and dynamics. A first clock frequency associated with a digital audio file may be increased to a second clock frequency, which speeds up the playback of the audio. The digital audio file may then be converted to analog at the higher second frequency, where it is further modified in the analog domain. The analog audio is then converted back into digital audio at the second clock frequency. The clock frequency is then decreased back to the first clock frequency for playback or storage of the processed (i.e., modified or manipulated) digital audio file. Alternatively, the entire process can take place in the digital domain.

主权项

1. A system for processing audio, the system comprising:
a processor that plays a downloaded digital audio file, wherein the digital audio file is associated with a first clock frequency to use for normal playback, wherein the processor causes the digital audio file to play faster than normal at a second clock frequency that is higher than the first clock frequency; a digital-to-analog converter that converts the digital audio into an analog audio signal while the digital audio is playing at the higher second clock frequency; an analog circuit that applies at least one of compression, limiting, and equalization to the analog audio signal; an analog-to-digital converter that converts the manipulated analog audio signal into manipulated digital audio; and a non-transitory computer-readable storage medium that stores the manipulated digital audio, wherein the processor causes the manipulated digital audio file to be associated with the first clock frequency for normal playback speed.
