Abstract: Systems and methods for audio editing are provided. In one implementation, a computer-implemented method is provided. The method includes receiving digital audio data and displaying a representation of the received digital audio data as an audio waveform. The display also includes a representation of one or more controls for applying one or more effects to the digital audio data. A user input is received manipulating a first control relative to the audio waveform. The displayed representation of the audio waveform is modified according to the relative position of the first control and a corresponding effect is applied to the digital audio data. The modified digital audio data is then made available for further processing.

Abstract: Systems, methods, and computer program products for editing digital audio data are provided. In some implementations a method is provided. The method includes receiving digital audio data incorporated in a plurality of audio tracks and receiving a selection of one or more audio tracks of the plurality of audio tracks for editing, the selected audio tracks being fewer than all of the plurality of audio tracks. The method also includes receiving an input specifying an audio effect to apply to the selected audio tracks and applying an inverse of the audio effect to one or more non-selected audio tracks in response to the input.

Abstract: Systems, methods, and computer program products for displaying audio data are provided. In some implementations, a computer-implemented method is provided. The method includes receiving audio data and displaying a composite image representing the audio data. The composite image combines a first representation and a distinct second representation of the audio data. Each representation is visible in the composite image and the representations appear in the composite image as if laid one over the other.

Abstract: This specification describes technologies relating to reducing audio masking. In general, one aspect of the subject matter described in this specification can be embodied in methods that include the actions of receiving a primary audio signal and a secondary audio signal; for each audio signal, calculating an average perceived intensity over time for each of a plurality of frequency bands; comparing the average perceived intensity of the secondary audio signal with the average perceived intensity of the primary audio signal for each frequency band; and for each frequency band where the average perceived intensity of the secondary audio signal is greater than the average perceived intensity of the primary audio signal by a specified threshold amount, attenuating the secondary audio signal by a specified amount to form a modified secondary audio signal.

Abstract: Methods, systems, and apparatus, including computer program products, for entering or editing musical note data. In one aspect, a method includes receiving a user input selecting a scale; receiving a user input of notes; determining whether each note is in the scale; and for each note that is not, automatically replacing the note with a corrected note. In another aspect, a method includes displaying a segment of music; receiving user input selecting a scale, multiple notes from the displayed music, and a pitch displacement; displacing the notes; and for each displaced note that is not in the scale, automatically replacing the displaced note with a corrected note. In another aspect, a method includes receiving user inputs selecting multiple scales and a non-overlapping period of time for each scale; receiving notes, each for a particular period; and correcting the notes as necessary according to the scale for the period.

Abstract: Embodiments relate generally to devices, methods and stimulus units for use in measuring neuromuscular function. Certain embodiments relate to a device for use in measuring at least one of nerve and muscle function, comprising: a substrate locatable on a body part, the substrate comprising a base portion, a limb portion and an intermediate portion located intermediate the base portion and the limb portion; first, second and third electrode pairs respectively located on the base, intermediate and limb portions; and wherein at least one of the first, second and third electrode pairs is usable as stimulation electrodes for providing a stimulus to the body part and at least another of the first, second and third electrodes is usable as sensing electrodes for sensing an electrical potential in the body part in response to the stimulus.
