Description by Maker Portal LLC Written by the developer, not by AppBrain. Click to read.
Biquadia is an acoustic engineering and audio analysis lab designed for audio engineers, researchers, and sound designers. It brings real-time DSP, acoustic measurement, spectral visualization, and spatial analysis directly to iOS and iPadOS.
[IN-APP PURCHASE DISCLOSURE]
Biquadia includes powerful core features completely free of charge. Advanced features marked below with [Requires In-App Purchase] require a Biquadia Pro subscription (Monthly with a 7-day free trial) or a Lifetime Purchase.
FREE FEATURES INCLUDED:
• DSP Lab: Real-time FIR/IIR filtering, parametric EQ, dynamics processing, live oscilloscope, and FFT spectrum analyzer.
• Analysis Lab: High-resolution FFT, pitch tracking, formant estimation, and real-time STFT spectrogram.
• Measurement Lab: Multi-sweep acoustic measurements, impulse response capture, and calibrated SPL analysis.
• Psychoacoustics & Codec Lab: Codec difference spectrograms, perceptual masking thresholds, and Bark/Mel scale overlays.
• Audio FX & Signal Generator: Sine, frequency sweeps, pink/white noise generator, plus chorus, drive, and delay visualization.
• System & Audio Hub: System performance diagnostics, multi-channel I/O mixer, and live signal routing meters.
PRO FEATURES [REQUIRES IN-APP PURCHASE]:
• Target-Speaker Extraction [Requires In-App Purchase]: Experimental on-device Core ML model that isolates one enrolled voice from a mixture using its speaker embedding — a technology demonstration, not a general-purpose noise remover.
• Advanced Array Processing [Requires In-App Purchase]: Covariance-based MVDR beamforming for multi-microphone arrays (up to 32 channels).
• Ambisonics & Spatial Audio [Requires In-App Purchase]: First-Order Ambisonics (FOA) encoding, 3D scene rotation, and binaural room impulse response decoding.
• Measurement Data Export [Requires In-App Purchase]: CSV export of per-band THD+N/SNR measurement data.
IN-APP PURCHASE OPTIONS:
- Biquadia Pro Monthly: $4.99/month (Auto-renewable subscription with a 7-day free trial).
- Biquadia Pro Lifetime: $79.99 (One-time non-consumable purchase).
Biquadia processes audio entirely on-device. It has no developer-operated backend, telemetry, or audio upload. Network activity is limited strictly to Apple StoreKit and user-selected external links.
