feat(audio): add an Audio Inspector tool (closes #94) - #95
Merged
Conversation
Import any audio file the browser can decode and see its duration, channel count, size, type and a waveform — decoded locally, nothing uploaded. No dependencies, no licensing. Because decodeAudioData resamples to the AudioContext's rate, the decoded sample rate is not the file's. So the true sample rate and bit depth are read straight from the WAV header when the file is a WAV; compressed formats contribute duration, channels and the waveform, with a note that sample rate/bit depth are WAV-only. - Pure formatting + WAV-header parsing (`audioInfo.js`) is unit-tested; the waveform reuses the editor's `computePeaks`. - Registered as the `audio-inspector` tool.
