# Tape Recorder Pro

**Tape Recorder Pro** is an advanced PyQt6-based audio application designed to simulate and calibrate analog tape machine recording and playback. Built with a powerful DSP backend using `numpy` and `scipy`, it provides auto-calibrating EQ capabilities, tape saturation emulation, and real-time audio playback and recording.

## Features

- **Auto-Calibrating EQ**: Automatically analyze and calibrate your audio signals to match specific frequency responses.
- **Tape Simulation**: Accurate emulation of tape saturation and safety filters (High-pass/Low-pass) for various tape types, including Type I (Ferric).
- **Comprehensive UI**: A multi-tab interface for device selection, calibration, EQ visualization, and media playback.
- **Real-time Processing**: Built on `sounddevice` for low-latency, real-time audio routing and processing.

## Installation

1. Ensure you have Python 3.8+ installed.
2. Install the required dependencies:
   ```bash
   pip install -r requirements.txt
   ```

## Usage

To launch the application, run the `main.py` script from the project root:

```bash
python main.py
```

### Application Tabs:
- **🔊 Devices**: Select your input and output audio devices.
- **📐 Calibrate**: Run the auto-calibration sequence to generate accurate EQ bands.
- **🎚️ EQ**: View and manually adjust the active EQ bands and saturation levels.
- **▶️ Player**: Play back audio files and apply the tape processor in real-time.

## Dependencies
- `sounddevice`
- `numpy` & `scipy`
- `soundfile` & `pydub`
- `PyQt6` & `pyqtgraph`
