Overview ¶

Package audio reads metadata out of audio containers.

SniffContainer works out the format from the file's first bytes, and Parse hands the data to that format's reader — MP3/ID3, FLAC, Ogg, WAVE, AIFF, AAC, AC-3, WMA/ASF, or MP4 — which fills in a Report: the common fields every format shares, the raw per-format tables, and any warnings the reader could not act on. Ported from CyberChef's lib/AudioParsers.mjs, AudioBytes.mjs and AudioMetaSchema.mjs.

Functions ¶

func Parse ¶

func Parse(b []byte, r *Report, container string, maxText int)

Parse hands the file to the reader for its container, or notes that there is not one.

Types ¶

type Container ¶

type Container struct {
	Typ string
	// contains filtered or unexported fields
}

Container is what the opening bytes of a file say it is.

func SniffContainer ¶

func SniffContainer(b []byte) Container

SniffContainer works out the container format from the file's first bytes. Some formats are named by a byte pattern at the very start, others by a four-character tag a little way in, so the two are looked for separately.

type Report ¶

type Report struct {
	Root *jsonval.OMap
	// contains filtered or unexported fields
}

Report is the document the operation builds. The pieces a parser reaches into are held separately so that they can be added to without walking back down from the root, while the root keeps the order everything is written in.

func NewReport ¶

func NewReport(filename string, byteLength int, c Container) *Report

NewReport builds the empty report a parser fills in.
