# Feature Specification: Auto Record and Save v1.0 - **Status**: 📋 Planned - **Version**: 1.0 (MVP) - **Author**: my name - **Created Date**: 2025-07-23 --- ## 1. Summary ### 1.1. Feature Overview This feature introduces a native audio recording capability directly within the SDLC Agent Workflow application. It allows users to capture audio from their microphone, save it as a standard MP3 file, and automatically load it into the transcription workflow. ### 1.2. Problem Solved Currently, users must record audio using external applications and then manually upload the resulting file. This creates friction and a disconnect between the real-world conversation (e.g., a project meeting) and the start of the automated SDLC process. ### 1.3. Value Proposition By integrating recording directly into the application, we: - **Streamline the Workflow**: Bridge the gap between live discussions and AI-powered analysis. - **Enhance User Experience**: Provide a seamless, all-in-one interface. - **Increase Automation**: Eliminate the manual steps of recording, saving, and uploading audio files. --- ## 2. User Workflow (MVP) The user experience for the Minimum Viable Product will be as follows: 1. **Navigate to UI**: The user opens the Gradio application. 2. **Locate Recorder**: A new UI section titled **"Record Audio"** is visible alongside the existing file upload options. 3. **Start Recording**: The user clicks the **"Start Recording"** button. - The button's text changes to **"Stop Recording"**. - A status indicator displays "Status: Recording..." along with a running timer (e.g., `00:01`, `00:02`). 4. **Capture Audio**: The application records audio from the user's default system microphone. 5. **Stop Recording**: The user clicks the **"Stop Recording"** button. - The recording is immediately finalized and saved. - The button reverts to **"Start Recording"**, and the status indicator shows "Status: Saved `recording_2025-07-23_103000.mp3`". - The file path of the newly created recording is **automatically populated** into the file input field of the transcription tool. 6. **Proceed with Workflow**: The user can now click the existing "Generate PRD" or "Transcribe" button to process the recorded audio without any further manual steps. --- ## 3. UI/UX Design ### 3.1. New UI Components - **Section**: A `Gradio.Box` or `Gradio.Group` titled "Record Audio". - **Button**: A `Gradio.Button` that toggles between "Start Recording" and "Stop Recording". - **Status Indicator**: A `Gradio.Textbox` or `Gradio.Markdown` element to display the recording status and timer. ### 3.2. Visual Mockup ``` +---------------------------------------------------+ | SDLC Agent Workflow | +---------------------------------------------------+ | | | [ Upload File ] [ Enter URL ] | | | | ------------------ OR ------------------- | | | | +-------------------------------------------+ | | | Record Audio | | | | | | | | [ Start Recording ] | | | | | | | | Status: Idle | | | +-------------------------------------------+ | | | | [ Transcribe & Generate key meeting ] | | | +---------------------------------------------------+ ``` --- ## 4. Technical Design & Implementation ### 4.1. New Service: `recording_service.py` - A new service will be created at `services/recording_service.py`. - **Responsibilities**: - Manage the audio recording stream. - Handle WAV-to-MP3 file conversion. - Manage file naming and saving to the `recordings/` directory. - **Threading Model**: The recording process must run in a background thread (`threading.Thread`) to prevent the Gradio UI from freezing. The service will use an event flag to signal when to stop recording. ### 4.2. New Dependencies The `pyproject.toml` file will be updated to include: - `sounddevice`: For capturing audio from the microphone. - `scipy`: For writing the captured NumPy array to a WAV file. - `pydub`: For converting the WAV file to MP3. A system-level dependency on **`ffmpeg`** will be required for `pydub` to function. ### 4.3. File Handling - A new directory, `recordings/`, will be created at the project root to store all recorded audio files. - This directory should be added to the `.gitignore` file. - **File Naming Convention**: `recording_YYYY-MM-DD_HHMMSS.mp3`. This ensures unique, sortable filenames. --- ## 5. Future Enhancements (Post-MVP) The following features are considered out of scope for v1.0 but are planned for future iterations: - **[ ] Pause and Resume**: Allow users to pause recording without terminating the session. - **[ ] Input Device Selection**: A dropdown menu to select the audio input device. - **[ ] Scheduled Recordings**: Integration with calendar events to trigger recordings automatically. - **[ ] System Audio Capture**: Record the system's output audio (e.g., from a video call), which is a more complex, OS-specific task. - **[ ] Automatic Silence Trimming**: Post-process the audio to remove dead air, optimizing the subsequent transcription.
