Nov 1, 2024In November 2024, the revisit-studies/study repo delivered two major features to enhance real-time audio capture, visualization, and playback, with a focus on reliability, provenance, and scalable storage. Real-time audio recording visualization was added via a RecordingAudioWaveform component, with a refactored audio upload flow and a new asynchronous model for creating/persisting audio streams. A separate feature introduced an audio replay UI and provenance-aware analysis playback, including component refactors for replay support, updated playback storage and a controller to manage audio streams and participant selection, and testing datasets for validation. Commit references include 867e73d3c053a269b3661636f9119cb570c59772 (fixing up audio), 600894107b515e37bb2bfc35bedd10929dce3710 (adding waveform vis), 9da56f4d59ecff7b54422167a4c7a23503d747be (being smarter about how to store the audio), 5779cf83759dfcbb0c66796820e6890a9fe42432 (audio replay UI), and 38db01a9dece0d592aa343e9918db65a20c9df0f (adding full replay stuff).
