Building a Carnatic Music Practice AppPublic

Since this is a new project (not an existing codebase), I don't need to explore existing code. Instead, I need to:

1. Understand the requirements better
2. Design the architecture
3. Ask clarifying questions about technology choices

Let me ask the user some key questions about their preferences for the tech stack and specific features.

Now let me create the Zustand store and then the UI components.

Now let me create the audio modules - TanpuraSynth and PitchDetector.

Now let me create the UI components and the practice engine hook. I'll complete the core functionality first.

Now let me create the UI components.

Now let me create the main App component to tie everything together.

Now let me install the dependencies and run the app to make sure it works. Let me also update the tasks.

The user wants:

• Web app
• Visual notation + audio (tanpura drone, reference tones)
• Cent-level precision (can show sharp/flat within a note)
• No gamaka detection (plain notes only)

Now I need to design the architecture. Let me launch a Plan agent to help design this, and also think about the technical approach myself.

Key components:

1. Frontend: React or vanilla JS web app
2. Audio Input: Web Audio API + pitch detection library (like pitchy, pitchfinder, or ml5.js)
3. Audio Output: Web Audio API for tanpura drone + reference tones
4. Music Data: JSON structures for ragams, compositions (sarali varisai etc.)
5. Analysis: Compare detected pitches with expected notes, calculate timing accuracy

Let me create a comprehensive plan.

Good, dependencies installed. Now let me run the build to check for any TypeScript errors.

There are a few TypeScript errors. Let me fix them.

I need to fix the TypeScript errors:

1. Remove unused Swara import
2. Fix the Float32Array type issue by using explicit casting
3. Remove unused SWARA_CENTS import from the hook

Now let me fix the usePracticeEngine hook by removing the unused SWARA_CENTS import.

I need to remove the unused import SWARA_CENTS from the hook file.

Now let me run TypeScript check again.

The Float32Array type is still an issue. Let me try a different approach - using as any or casting properly.

Let me just use as any to bypass this type issue, since the runtime behavior will be correct.

Let me check TypeScript again.

The error is on line 67 which is the getFloatTimeDomainData call, not the findPitch call. Let me read the file again to see the current state.

That's a comprehensive design from the Plan agent. Now let me write this into the plan file and then exit plan mode for user approval.

Let me create the plan file with a concise, actionable summary.

The issue is with getFloatTimeDomainData. This is a standard Web Audio API method and the TypeScript typing might be off. Let me skip strict typing for this file by using a type assertion.

Let me check TypeScript again.

Let me try a different approach - disable type checking for this specific operation or use a different cast.

Let me check TypeScript again.

TypeScript passes. Now let me run the dev server to make sure the app actually works.

The dev server is running. The app is ready to use at http://localhost:5173/. Let me provide a summary to the user.

The user wants to build a Carnatic music practice app with these features:

1. Settings/Configuration:

   • Base pitch selection (e.g., D is Sa)
   • BPM (e.g., 33 bpm)
   • Speed/Gati (1 note per beat, 2 notes per beat, 4 notes per beat)
   • Ragam (scale) selection
   • Composition selection (e.g., Sarali Varisai 1, 2, etc.)

2. Practice Mode:

   • User sings along to the app
   • App presumably plays/shows the expected notes

3. Feedback/Analysis:

   • After singing, show which notes were wrong
   • Show where timing/beat was off

This is a fairly complex application involving:

• Audio processing (pitch detection from voice)
• Music theory (Carnatic ragams, swaras)
• Timing analysis
• UI for configuration and feedback

Let me first check the reference link to understand what kind of content they're referring to, then plan the architecture.

This is a non-trivial task that would benefit from planning. Let me enter plan mode to properly design this.

The user has several issues and feature requests:

1. Bug: Can't hear tanpura - Need to debug the tanpura synth
2. Bug: Showing Janta Varisai instead of Sarali - There's a bug in the exercise selector
3. Missing: Metronome - Need to add a metronome/click track
4. Feature request: Recording playback - Record the voice and play it back
5. Feature request: Visual recording analysis - Show a visualization of the recording with:
   • Where they went off pitch
   • Where they were flat/sharp
   • Map this to specific notes in the exercise

Let me fix the bugs first, then add the recording/playback feature with visualization.

First, let me look at the ExerciseSelector to see why it's showing Janta Varisai.

The ExerciseSelector looks fine. Let me check the NotationDisplay to see what's showing. Also, let me check the exercises data to see if Janta is somehow mixed up.

The display shows exercise.name which comes from the data. Let me check if the sarali varisai is actually named correctly. Also let me check the categories definition.

The CATEGORIES includes Janta as an option, but there's no data for it, so when you select Janta it shows "Coming soon...". But the actual sarali varisai data should be fine. Let me check the sarali data names.Actually the user said they see "Janta Varisai" even when picking Sarali. That's odd. Let me check the sarali data more carefully to see if any exercise is mislabeled.

Actually, wait - the sarali exercises have name: 'Sarali Varisai 1' etc. So that should display correctly. Maybe there's an issue with how the exercise name is getting displayed or maybe the user is confused.

Let me focus on the main issues:

1. Tanpura not playing - need to debug TanpuraSynth
2. Add metronome
3. Add recording playback with visualization

Let me first check the TanpuraSynth to see why it's not playing.

I see the issue with TanpuraSynth. When stop() is called, it sets isPlaying = false immediately, but then when start() is called again, the old audio context might still be around but the oscillators array is empty. Also, the stop() method might be getting called somewhere that's not expected.Let me trace through:1. In start(): If isPlaying is true, it calls stop() first2. stop() immediately sets isPlaying = false3. Then start() continues...Actually I think the issue might be that after calling stop(), we're immediately trying to create new oscillators on the same audio context. But the cleanup happens asynchronously (setTimeout 350ms), so the new oscillators might conflict.

Let me rewrite the TanpuraSynth to be more robust. Also, I need to add:

1. Metronome click
2. Audio recording and playback with visualization

Let me create a comprehensive update.

Now let me create a Metronome class and update the types to include recording data.

Good, I've written the plan. Now I should exit plan mode to get user approval.

Now let me create a Recording class that can record audio and store pitch data for playback visualization.

Now I need to update the store to include recording data and metronome settings.

Now let me update the types to include metronome settings.

Let me update the types to include metronome settings.

Now let me update the practice engine to include recording and metronome.

Now let me update the SettingsPanel to include metronome toggle.

Now let me create a RecordingPlayback component with visualization for the feedback panel.

Now I need to update the FeedbackPanel to include the RecordingPlayback component.

Let me check for TypeScript errors and fix any issues.

I need to fix these unused variable warnings. Let me clean them up.

The user has approved the plan. Now I can start implementing. Let me create the tasks and start building the app.

I'll start with:

1. Phase 1: Project setup + data
2. Phase 2: Settings + Exercise UI
3. And so on...

Let me create the tasks first, then start implementing.

I also need to update the call site for analyzeFramesByNote since I changed the signature.
