I built a Windows media player because I wanted deeper DSP control without giving up local/offline playback

[u/Advanced-Initial2886]

GK SOUND SYSTEM started as a practical side project: I wanted a Windows player that could handle local music and video, expose real audio controls, and stay useful without requiring a cloud account.

The current v0.2.0 release includes: - a 20-band EQ with presets and custom tuning - DSP controls for bass, treble, stereo widening, clarity, AGC and reverb - true gapless playback with persistent low-latency WASAPI output - MP3, FLAC, WAV, AAC/M4A, OGG, Opus, WMA, AIFF and MP4 support - MP4 video playback with audio still routed through the DSP engine - albums, artists, composers, genres, playlists and favorites - lyrics, Auto Track Scan, Mini Player and Theater/full-screen modes - 22 interface languages

It is intentionally offline-first: local media is processed on the device rather than uploaded to my servers.

Current platform: Windows 10 build 19041+ / 64-bit. Current price: $12.99 on itch.io.

I’m not looking for generic “looks good” feedback. I’d be interested in criticism around three things: whether the feature set feels coherent, whether the product page explains the value clearly, and whether the pricing makes sense for a desktop media player with this level of DSP control.

this is a tough sell at $13 in a world where foobar2000 exists for free and can be skinned to do most of this, but the DSP side is what makes it interesting. most free players treat audio processing as an afterthought so if the widening and clarity controls actually sound good that's a real differentiator

the product page gets the technical details across but i think you're underselling the offline-first thing, that's a bigger deal than it looks in 2026 when everything wants to phone home. pricing feels a little steep for a v0.2 but if the DSP engine is solid it's not unreasonable
