What is claimed is:

1. A method of processing an audio recording for facilitating production of

competitively loud mastered audio recording with reduced distortion, the method comprising:

receiving, using a communication device, an audio file comprising the audio recording from an electronic device;

providing, using a first attenuator, a first attenuation to the audio recording to produce a first attenuated audio recording;

routing the first attenuated audio recording onto an input of a first bus; providing, using a second attenuator, a second attenuation to the first attenuated audio recording available at an output of the first bus to generate a second attenuated audio recording;

routing the second attenuated audio recording onto an input of a second bus;

providing, using a third attenuator, a third attenuation to the second attenuated audio recording available at an output of the second bus to generate a third attenuated audio recording;

processing, using a two-stage dual limiter, the third attenuated audio recording to generate a track output, wherein the two-stage dual limiter comprises a first stage and a second stage, wherein the first stage is configured for preventing compression of at least one of predetermined low frequencies and predetermined high frequencies in the third attenuated audio recording, wherein the second stage is configured for preventing transient peaks in the third attenuated audio recording from approaching digital zero; and

transmitting, using the communication device, the track output to the electronic device.

2. The method of claim 1 , wherein the audio recording comprises an unprocessed, mixed digital audio recording.

The method of claim 1 , wherein the audio recording comprises a mastered digital audio recording.

The method of claim 3 further comprising providing, using an additional attenuator, an additional attenuation to the first attenuated audio recording prior to routing the first attenuated audio recording onto the first bus.

The method of claim 1 , wherein the first stage of the two-stage dual limiter comprises at least one of a Low Pass Filter (LPF) and a High Pass Filter (HPF).

The method of claim 1 further comprising providing, using an amplifier, a makeup gain to the third attenuated audio recording available at an output of the first stage of the two-stage dual limiter.

The method of claim 6 further comprising applying, using a dithering device, dithering to at least one predetermined low frequency in the third attenuated audio recording available at an output of the amplifier.

The method of claim 1 , wherein the second stage of the two-stage dual limiter comprises a brickwall compressor.

The method of claim 1 further comprising equalizing, using an equalizer, the first attenuated audio recording prior to routing the first attenuated audio recording onto the first bus.

The method of claim 1 further comprising routing the first attenuated audio recording to inputs of each of a primary track send and a clone track send via a split-send of the output of the first bus, wherein a primary Sound Pressure Level (SPL) associated with the primary track send is identical to a clone SPL associated with the clone track send, wherein outputs of each of the primary track send and the clone track send are routed to the input of the second bus.

11. The method of claim 10, wherein routing of each of the primary track send and the clone track send to the input of the second bus causes wave interference and results in increased SPL.

12. The method of claim 1, wherein providing at least one of the first attenuation, the second attenuation and the third attenuation enables production of a competitively loud mastered audio recording without clipping digital zero, thereby avoiding digital square wave distortion.

13. The method of claim 1, wherein at least one of the first attenuation, the second attenuation and the third attenuation may correspond to a volume level below at least one of the Root Mean Square (RMS) value and a Peak Volume Level.

14. The method of claim 4, wherein the additional attenuation is configured to

compensate for inherent differences in dynamic range and Sound Pressure Level encountered when processing the mastered digital audio recording.

15. The method of claim 7, wherein the dithering is configured to reduce an audible distortion created by the makeup gain.

16. A system for processing an audio recording for facilitating production of

competitively loud mastered audio recording with reduced distortion, the system comprising:

a communication device configured for:

receiving an audio file comprising the audio recording from an electronic device; and

transmitting a track output to the electronic device;

a first attenuator configured for providing a first attenuation to the audio recording to produce a first attenuated audio recording, wherein the first attenuated audio recording is routed onto an input of a first bus;

a second attenuator configured for providing a second attenuation to the first attenuated audio recording available at an output of the first bus to generate a second attenuated audio recording, wherein the second attenuated audio recording is routed onto an input of a second bus;

a third attenuator configured for providing a third attenuation to the second attenuated audio recording available at an output of the second bus to generate a third attenuated audio recording; and

a two-stage dual limiter configured for processing the third attenuated audio recording to generate the track output, wherein the two-stage dual limiter comprises a first stage and a second stage, wherein the first stage is configured for preventing compression of at least one of predetermined low frequencies and predetermined high frequencies in the third attenuated audio recording, wherein the second stage is configured for preventing transient peaks in the third attenuated audio recording from approaching digital zero.

17. The system of claim 16, wherein the audio recording comprises an unprocessed, mixed digital audio recording.

18. The system of claim 16, wherein the audio recording comprises a mastered digital audio recording.

19. The system of claim 18 further comprising an additional attenuator configured for providing an additional attenuation to the first attenuated audio recording prior to routing the first attenuated audio recording onto the first bus.

20. The system of claim 16, wherein the first stage of the two-stage dual limiter

comprises at least one of a Low Pass Filter (LPF) and a High Pass Filter (HPF).

21. The system of claim 16 further comprising an amplifier configure for providing a makeup gain to the third attenuated audio recording available at an output of the first stage of the two-stage dual limiter.

22. The system of claim 16 further comprising a dithering device configured for applying dithering to at least one predetermined low frequency in the third attenuated audio recording available at an output of the amplifier.

23. The system of claim 16, wherein the second stage of the two-stage dual limiter comprises a brickwall compressor.

24. The system of claim 16 further comprising an equalizer configured for equalizing the first attenuated audio recording prior to routing the first attenuated audio recording onto the first bus.
