摘要： A Device Echo Cancellation system and process are disclosed. According to one embodiment, the present invention comprises an input audio source that is converted to a digital signal via a PCM convertor where the amplitude of the input audio source is sampled at regular intervals and translated into digital PCM audio. The resulting PCM audio is analyzed for its dynamic and harmonic content. Corrective sound waves are then generated that reduce the repetition of the original audio (echoes). The corrective sound waves are applied to the repeating audio echoes to create corrected sound waves. The corrected audio is then outputted from the system. The analyzing step of the Device Echo Cancellation process of the present invention comprises performing an evaluation of the PCM audio for dynamic and harmonic content; identifying repetitive harmonic content (echoes) of the PCM audio; determining a scale based on the ratio of the amplitude of the first repeat harmonic to the amplitude of the input PCM audio; generating sound waves with descending amplitude levels according to the determined scale; and phase shifting the newly generated sound waves to generate corrective sound waves. The phase shift of the inventive Device Echo Cancellation process is 90 to 180 degrees.

摘要： A process and system for enhancing and customizing sound includes receiving an input audio sound and enhancing the voice audio input in two or more harmonic and dynamic ranges by re-synthesizing the audio into a full range PCM wave. A tone adjusting circuit is provided which includes a first section for adjusting a low frequency tone, a second section for adjusting a mid frequency tone, a third section for adjusting a high frequency tone and mixing the audio outputs processed by the first, second and third sections to produce an output audio sound. The enhancement includes the parallel processing the input audio via a low pass filter with dynamic offset, an envelope controlled bandpass filter, a high pass filter, adding an amount of dynamic synthesized sub bass to the audio and combining the four treated audio signals in a summing mixer with the original audio. The low frequency tone has a frequency of 100 Hz and a bandwidth of 0.5. The mid frequency tone has a frequency of 2500 Hz and an adjustable bandwidth and the high frequency tone has a frequency of 10 KHz and an adjustable bandwidth.

摘要： A Noise Cancellation Process for Aircraft is disclosed. According to one embodiment, an input audio source corresponding to sound received from multiple microphones situated equidistantly in both directions in a two dimensional plane, is converted to a digital signal via an analog to digital (A/D) convertor. The A/D converted audio is analyzed for content to identify ambient noise. The frequency, amplitude and phase of the identified ambient noise is subsequently determined. A Noise correction sound wave is generated with negative phase of that corresponding to the identified ambient noise. The noise correction sound wave is added to the identified noise to create a noise corrected sound.

摘要： A process and system for enhancing and customizing audio recording and editing comprises receiving an input audio sound; setting a preset for the input audio sound to create a presetted audio sound; tone adjusting the presetted audio sound to create a tone adjusted presetted audio; expanding the tone adjusted presetted audio in a horizontal plane to create an presetted tone adjusted expanded audio; and outputting the presetted tone adjusted expanded audio. There are three options for selecting the preset. These are: ten or more presets for different genres of music; auto-preset that is selected by genre in metadata of playback material; and a single generic preset that covers all music. Presetting comprises parallel processing the input audio through: a module that is a low pass filter with dynamic offset; an envelope controlled bandpass filter; a high pass filter; adding an amount of dynamic synthesized sub bass to the audio; and combining the four treated audio signals in a summing mixer with the original audio. The adjustment step comprises a first section for adjusting a low frequency tone; a second section for adjusting a mid frequency tone; a third section for adjusting a high frequency tone; and mixing the audio outputs processed by the first, second and third sections to produce an output audio sound.

摘要： A Noise Cancellation Process for a motorcycle comprising an input audio source. Input audio source is combined in a mixer. Noise analyzer analyzes output from the mixer for amplitude and harmonic content. A replicate wave that is identical to the input audio source is created. The phase of the replicate wave is changed by −180 degrees. Amplitude from the Noise Analyzer is monitored and amplitude of the replicated wave is matched to the original wave. The phase of the replicate wave and the input audio wave are combined to create Audio Out. Audio Out is played on the system.

摘要： An audio enhancement technique comprises an audio source. The audio source is split into at least two branches and each of the branches is processed by a filter bank. Outputs from the filer banks are summed up to create a summed output signal. The summed output signal is splitting into two or more segments to create a split summed output signal. The split summed output signal is processed by one or more audio processing modules. Audio processed by each of the audio processing modules is summed to create a summed audio processed signal. The summed audio processed signal is provided to a balance module to select a balance mix of the audio source and the summed audio processed signal to create a balanced mixed audio signal. The balanced mixed audio signal is fed to a stereo output gain module for gain adjustment to create a gain adjusted stereo signal. The phase of the gain adjusted stereo signal is optionally changed in an amount between zero and 180 degrees to create a final output signal, which is sent to a playback device selected by user.
