# Bhargava Swara

A Python library for analyzing and visualizing Indian classical music, including spectrogram generation (Mel-frequency, Chroma, CQT, and Cent filterbank), raga, tala, tempo, tradition, ornaments, and full analysis.

## Prerequisites

- **Gemini API Key:**  
  This library uses Google's Gemini API for music analysis. To obtain a key:  
  1. Sign up for a Google Cloud account  
  2. Enable the Generative AI API in the Google Cloud Console  
  3. Create an API key in the "Credentials" section  
  Refer to [Google's Generative AI Docs](https://cloud.google.com/generative-ai/docs) for details

- **Audio Files:**  
  Supported formats include WAV and MP3 for analysis and spectrogram generation

## Installation

Install the library using pip:

```sh
pip install bhargava_swara
```

## Dependencies

- `google-generativeai>=0.1.0`  
- `librosa>=0.10.0`  
- `matplotlib>=3.7.0`  
- `numpy>=1.24.0`

## Spectrogram Generation

Generate various types of spectrograms to visualize different aspects of audio frequency content over time.

### Mel-Frequency Spectrogram
```python
from bhargava_swara import generate_mel_spectrogram

audio = "path/to/audio.wav"
output = "path/to/output_mel_spectrogram.png"
generate_mel_spectrogram(audio, output, n_mels=128, fmax=8000)
print("Mel spectrogram generated successfully!")
```

#### Spectrogram Parameters:
- `audio`: Path to the input audio file (e.g., WAV or MP3)
- `output`: Path to save the PNG file
- Mel-specific: `n_mels` (default: 128), `fmax` (default: 8000)

## Music Analysis

Analyze various aspects of Indian classical music using the Gemini API.

### Raga Analysis
```python
from bhargava_swara import analyze_raga

api_key = "YOUR_API_KEY"
audio = "path/to/audio.wav"
result = analyze_raga(audio, api_key)
print(f"Raga: {result}")
```

### Tala Analysis
```python
from bhargava_swara import analyze_tala

api_key = "YOUR_API_KEY"
audio = "path/to/audio.wav"
result = analyze_tala(audio, api_key)
print(f"Tala: {result}")
```

### Tempo Analysis
```python
from bhargava_swara import analyze_tempo

api_key = "YOUR_API_KEY"
audio = "path/to/audio.wav"
result = analyze_tempo(audio, api_key)
print(f"Tempo: {result}")
```

### Tradition Analysis
```python
from bhargava_swara import analyze_tradition

api_key = "YOUR_API_KEY"
audio = "path/to/audio.wav"
result = analyze_tradition(audio, api_key)
print(f"Tradition: {result}")
```

### Ornament Analysis
```python
from bhargava_swara import analyze_ornaments

api_key = "YOUR_API_KEY"
audio = "path/to/audio.wav"
result = analyze_ornaments(audio, api_key)
print(f"Ornaments: {result}")
```

### Full Music Analysis
```python
from bhargava_swara import analyze_music_full

api_key = "YOUR_API_KEY"
audio = "path/to/audio.wav"
result = analyze_music_full(audio, api_key)
print(f"Full Analysis:\n{result}")
```

## Music Synthesis

Create Indian classical music elements with ease.

### Tanpura Drone
Generate a tanpura drone for practice or ambiance.

```python
from bhargava_swara import generate_tanpura_drone

# Play in real-time
generate_tanpura_drone(pitch=261.63, duration=10)

# Save to WAV
generate_tanpura_drone(pitch=261.63, duration=10, output_path="tanpura_drone.wav")
```

#### Parameters:
- `pitch`: Fundamental frequency of Sa (e.g., 261.63 Hz for C4)
- `duration`: Length of the drone in seconds
- `output_path`: Path to save WAV file (optional; if None, plays in real-time)

## Future Development

We plan to enhance Bhargava Swara with the following features:

### Spectrogram Enhancements
- **Chroma Spectrogram**: Add support for visualizing pitch class distributions over time.
- **CQT Spectrogram**: Implement constant-Q transform spectrograms for better frequency resolution.
- **Cent Filterbank Spectrogram**: Generate spectrograms using cent-scaled filterbanks for microtonal analysis.

### Analysis Features
- **Automatic Raga Recognition**: Develop algorithms to identify ragas automatically from audio input.
- **Tonic Identification**: Detect the tonic (base pitch) of a performance for accurate analysis.
- **Pitch Extraction**: Extract pitch contours from audio to analyze melodic structure.
- **Rhythm Analysis**: Analyze meter, rhythmic patterns, and structure in talas.

### Synthesis Tools
- **Tala Generation**: Create rhythmic cycles (talas) programmatically for practice or composition.
- **Generate Music Based on Raga**: Synthesize music adhering to a specific raga's rules.
- **Music Imitation**: Generate music imitating the style of a given audio input.

Contributions and suggestions for these features are welcome! Please submit ideas or pull requests to the [GitHub repository](https://github.com/your-repo/bhargava_swara).
