Frequently Asked Questions
What is a real-time spectrum analyzer?
A real-time spectrum analyzer is a professional audio tool that displays the frequency content of an audio signal as it's playing. It uses FFT (Fast Fourier Transform) to break down complex audio into individual frequency components, showing you exactly what frequencies are present at any given moment. This is essential for mixing, mastering, and audio analysis.
How does FFT spectrum analysis work?
FFT (Fast Fourier Transform) is an algorithm that converts time-domain audio signals into frequency-domain data. SoundAnalyzer samples your audio, applies FFT processing with selectable sizes from 1024 to 16384 points, and displays the resulting frequency spectrum in real-time. Higher FFT sizes provide better frequency resolution but slightly slower response.
Can I use SoundAnalyzer as a VST3 plugin?
Yes! SoundAnalyzer works both as a VST3 plugin and as a standalone application. The VST3 version integrates seamlessly with all major DAWs including FL Studio, Ableton Live, Cubase, Pro Tools, Logic Pro, and Reaper. Simply load it on any channel to analyze that track's frequency content.
Does it capture system audio automatically?
Absolutely! SoundAnalyzer includes built-in WASAPI loopback audio capture, which means it can analyze any audio playing on your Windows computer without any additional configuration or virtual audio cables. Just launch the standalone version and it immediately starts capturing and analyzing your system audio.
What makes SoundAnalyzer different from free alternatives?
While free spectrum analyzers exist, SoundAnalyzer combines professional-grade FFT analysis, built-in WASAPI system audio capture, modern UI, multiple windowing functions, configurable FFT sizes, peak hold, and low CPU usage—all in one package for just $5. Most free alternatives lack system audio capture or have outdated interfaces.
Is there a free trial available?
We offer a 30-day money-back guarantee with every purchase. If SoundAnalyzer doesn't meet your expectations, simply email us at xyaudiomail@gmail.com for a full refund. At only $5, it's an affordable way to get professional spectrum analysis capabilities.
What are the system requirements?
SoundAnalyzer requires Windows 10 or 11 (64-bit), an Intel i5 or AMD equivalent processor, and at least 4GB RAM (8GB recommended). It works with any WASAPI-compatible audio interface and supports sample rates from 44.1kHz to 192kHz. Still the app may run on much lower specs with high performance it is a lightweight application. These are just general recommendations.
Is there a 32-bit version available?
A 32-bit version is available upon request - please contact us at xyaudiomail@gmail.com with your purchase receipt.
Which windowing functions are included?
SoundAnalyzer includes all professional windowing functions: Hann, Hamming, Blackman, and Rectangular. Each window type is optimized for different analysis scenarios. Hann is great for general use, Blackman for high dynamic range, and Rectangular for transient analysis.
