Spectral Detail — High-resolution offline audio spectral analysis

Spectral Detail

See the recording, not a summary of it.

A high-resolution offline spectral analysis viewer for audio. It reads the file once, analyses it properly rather than in a real-time budget, and renders the result on the GPU so you can actually move around inside it.

Private Rust & C++ GPU rendered

Offline is the point.

A real-time analyzer has to finish before the next audio buffer arrives, and every design decision inside it bends to that deadline: smaller transform sizes, coarser frequency resolution, decimated drawing. That is the correct trade when you are tracking a live signal, and the wrong one when you are examining a file.

Spectral Detail drops the deadline. It decodes the whole file, runs the analysis across every core, and keeps the resolution that a real-time tool has to throw away. What you get back is a spectrogram detailed enough to find the thing you were actually looking for.

How it is put together.

High-resolution FFT

Analysis runs offline and in parallel across cores, so transform size is chosen for the detail you want rather than for what fits in a buffer deadline.

GPU-accelerated view

The interface renders through the GPU, which is what keeps panning and zooming across a long, dense spectrogram responsive instead of a slideshow.

Reads what you have

Broad codec and container support through a full decoding stack, so the file you were handed opens without a conversion step first.

Rust with a C++ core

Rust for the application, interface, and audio plumbing, with a C++ analysis core bridged across a typed boundary rather than a pile of raw pointers.
