Abstract
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.
Claims19
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.
A method for mastering digital audio, the method including steps comprising:
- downloading a digital audio file having a first clock frequency for playback;
- outputting, for modification, a representation of audio based on a second clock frequency that is higher than the first clock frequency, wherein the representation of audio comprises one of the digital audio file or a representative analog signal, wherein the modification includes at least one of compression, equalization, and limiting;
- receiving a modified representation of the audio based on the second clock frequency;
- storing the modified representation of the audio as a modified digital audio file;
- and
- converting the clock frequency of the modified digital audio file to the first clock frequency.
An audio processing device, comprising:
- an input interface that downloads and stores at least a portion of a digital audio file that has a first clock frequency for normal playback;
- a processor that increases the playback clock frequency of the digital audio to a higher second frequency without converting the sample rate of the digital audio;
- a digital-to-analog converter that converts the digital audio to analog audio at the second clock speed;
- an analog modification circuit that applies at least one of compression, limiting, and equalization to the analog audio;
- an analog-to-digital converter that converts the modified analog audio to modified digital audio;
- a non-transitory computer-readable storage medium that stores the modified digital audio, wherein the modified digital audio is thereafter assigned the first clock frequency for normal playback;
- and
- an output interface that outputs the modified digital audio.
