Some embodiments of the invention are directed to enabling a user to easily identify the frequency range(s) at which sound masking occurs, and addressing the masking, if desired. In this respect, the extent to which a first stem is masked by one or more second stems in a frequency range may depend not only on the absolute value of the energy of the second stem(s) in the frequency range, but also on the relative energy of the first stem with respect to the second stem(s) in the frequency range. Accordingly, some embodiments are directed to modeling sound masking as a function of the energy of the stem being masked and of the relative energy of the masked stem with respect to the masking stem(s) in the frequency range, such as by modeling sound masking as loudness loss, a value indicative of the reduction in loudness of a stem of interest caused by the presence of one or more other stems in a frequency range.

Some embodiments of the invention are directed to techniques for suppressing or attenuating noise in audio circuitry, such as which may result from a source of electromagnetic energy being coupled to the audio circuitry. Some embodiments may employ two separate channels, a first of which captures audio information and noise, and a second of which captures the noise. Noise compensation may be performed by transforming the signal of the first channel in accordance with noise in the second channel which is identified as comprising a particular type of noise.

Some embodiments of the invention are directed to enabling a user to modify the manner in which one or more settings specified by a predefined template for a particular sound source are applied, so as to provide the user with greater control over the settings which are applied to a track than conventional tools afford. Some embodiments are directed to automatically applying one or more settings for a track based at least in part upon an analysis of the spectral and/or dynamic content of the track, such as by automatically performing sound equalization by applying one or more digital filters to a track, defining the frequency range(s) in which one or more filter(s) are applied, applying dynamic range compression, defining the manner in which compression is applied in multiple sub-bands of the audible spectrum, and/or applying one or more other settings. Such settings may be designed to achieve any of numerous (e.g., artistic) goals, such as to bring to the forefront certain elements of the natural character of the sound in a track, or to enhance the track's overall balance and/or clarity.
Some embodiments of the invention are directed to an audio production system which is more portable, less expensive, faster to set up, and simpler and easier to use than conventional audio production tools. An audio production system implemented in accordance with some embodiments of the invention may therefore be more accessible to the typical user, and easier and more enjoyable to use, than conventional audio production tools.

A novel system and method for adjusting the dynamic range of an audio recording or signal, which does not require user manipulation of threshold and ratio (and other parameters). Unlike prior audio compressors or limiters, the present invention provides for the ability to set the dynamic range without complicated user settings and knowledge. The process can be done automatically by a computer or processor.
A system and method for limiting amplitude of a signal, such as limiting the loudness of an audio signal. Embodiments of the present invention allow for the most aggressive limiting by using an advanced psychoacoustic model to intelligently determine the amount of limiting that can be done to the incoming signal before producing distortion that is detectable to the human ear.

A system and method for displaying, playing and modifying song and percussion sequences. Users can easily view and modify such sequences using a User Interface (UI), including while the sequences are playing. A user may quickly “zoom in” on specific sounds and rhythms, and modify the sound and/or rhythm while it plays. Users can also “zoom out” to view and manipulate a song at a pattern level, or at a song level with multiple sections of different sounds and rhythms.

A pickup processing system for a guitar or other musical instrument. According to one embodiment, a split pickup is employed that separates the sound from the two bass strings from the other four strings. The signal from the bass strings may be provided to an octave divider, which creates a bass sound to add back into the sound. The octave divider produces sound without discontinuities or other artifacts. Other effects include restored acoustical properties of the guitar body, stereo imaging, reverb and others. The present invention may be fully contained within the body of an acoustic guitar.

A system and method to assist a singer or other user. An audio source is processed to extract the lead vocals from the audio signal. This vocal signal is fed to a pitch detection processor which estimates the pitch at each moment in time. A user singing into a microphone provides a user vocal signal that is also pitch detected. The pitch of the lead vocal signal and the user vocal signal are compared and any difference is provided to a pitch shifting module, which then can correct the pitch of the user vocal signal. The corrected user vocal signal may be combined with a background signal comprising a signal from the audio source without the lead vocal signal, and then provided to headphones or loudspeakers to the user and/or an audience. This system and method may be used for Karaoke performances.

Controlling a multimedia software application using high-level metadata features and symbolic object labels derived from an audio source, wherein a first-pass of low-level signal analysis is performed, followed by a stage of statistical and perceptual processing, followed by a symbolic machine-learning or data-mining processing component is disclosed. This multi-stage analysis system delivers high-level metadata features, sound object identifiers, stream labels or other symbolic metadata to the application scripts or programs, which use the data to configure processing chains, or map it to other media. Embodiments of the invention can be incorporated into multimedia content players, musical instruments, recording studio equipment, installed and live sound equipment, broadcast equipment, metadata-generation applications, software-as-a-service applications, search engines, and mobile devices.
