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.
