Overview

Package soundanalysis provides a fluent Go API over the macOS SoundAnalysis framework.

Construction

New… functions create objects; each With… method sets one property and returns its receiver, so configuration calls chain. A <Type>FromID constructor adopts an Objective-C object obtained elsewhere.

Lifecycle

A wrapper releases its Objective-C object automatically once the garbage collector finds it unreachable. Call Release to relinquish the reference deterministically (for objects holding scarce resources); Release is idempotent, and afterwards the wrapper's methods are no-ops returning zero values.

Errors

Failing calls return errors carrying the Objective-C error domain and code. Match them against this package's Err… sentinel values with errors.Is, or inspect domain, code, and Apple's prose via errors.As with *errkit.Error.

func (*ClassifySoundRequest) OverlapFactor added in v0.17.0 

func (csr *ClassifySoundRequest) OverlapFactor() float64

OverlapFactor returns the overlap factor of the windows of audio data provided to the classifier, if the model operates on fixed audio block sizes. When performing audio analysis on fixed audio block sizes, it is common for the analysis windows to overlap by some factor. Without overlapping the analysis windows (when the overlap factor is 0.0), a sound might be split across two analysis windows, which could negatively affect classification performance. Overlapping the analysis windows by 50% ensures each sound will fall near the center of at least one analysis window. The supported range is [0.0, 1.0), and the default value is 0.5. Increasing the overlap factor increases computational complexity, so values greater than 0.5 should be used with care.

func (*ClassifySoundRequest) String added in v0.17.0 

func (csr *ClassifySoundRequest) String() string

String returns the object's -description text, so a wrapper prints usefully under fmt.

func (*ClassifySoundRequest) WindowDuration added in v0.17.0 

func (csr *ClassifySoundRequest) WindowDuration() coremedia.CMTime

WindowDuration returns the duration of a single analysis window. When performing classification over an audio stream, a classifier computes each classification result based on a single 'analysis window' of audio. Analysis windows are uniformly-sized time intervals, where the size of any given window is considered that window's 'duration'. Some classifiers can operate over analysis windows which conform to one of several different duration options. Larger window durations allow classification to execute less frequently over larger contexts of audio, potentially improving classification performance. Smaller window durations allow classification to execute more frequently over smaller contexts of audio, producing results with sharper time resolution. Depending on the use-case, a larger or smaller window may be preferable. When configuring the window duration, it is important to respect the capabilities of the classifier. A classifier's supported window durations can be discovered using the `windowDurationConstraint` property. If an unsupported window duration is selected, the window duration will be automatically rounded down to the nearest supported value if possible, else rounded up.

func (*ClassifySoundRequest) WindowDurationConstraint added in v0.17.0 

func (csr *ClassifySoundRequest) WindowDurationConstraint() *TimeDurationConstraint

WindowDurationConstraint returns the constraints governing permitted analysis window durations. The analysis window duration is controlled using the `windowDuration` property. If an analysis window duration is selected which does not meet the necessary constraints, it will automatically be adjusted to meet these constraints (see `windowDuration` for more information regarding how this adjustment will be applied).

func (*ClassifySoundRequest) WithOverlapFactor added in v0.17.0 

func (csr *ClassifySoundRequest) WithOverlapFactor(overlapFactor float64) *ClassifySoundRequest

WithOverlapFactor sets the amount of overlap between successive analysis windows when the model operates on a fixed-size audio block.

func (*ClassifySoundRequest) WithWindowDuration added in v0.17.0 

func (csr *ClassifySoundRequest) WithWindowDuration(windowDuration coremedia.CMTime) *ClassifySoundRequest

WithWindowDuration sets the duration of the audio buffer the request sends to the underlying sound classifier for each prediction.

DurationRange returns if the constraint type is range, then the range of allowable window durations. - Returns: If the constraint type is range, a CMTimeRange representing the range of allowable window durations. If the constraint type is not range, `kCMTimeRangeInvalid`. The `type` property should be queried before this property is accessed. This property will only yield meaningful values if the constraint type is considered to be 'range'. The constraint type is considered to be 'range' if the `type` property is equal to `SNTimeDurationConstraintTypeRange`.

The durations will always be provided sorted in order of ascending time. If the constraint type is not enumerated, an empty array will be returned. The `type` property should be queried before this property is accessed. This property will only yield meaningful values if the constraint type is considered to be 'enumerated'. The constraint type is considered to be 'enumerated' if the `type` property is equal to `SNTimeDurationConstraintTypeEnumerated`.

EnumeratedDurations returns the collection as a Go slice.
