dsp

Until now, I kept things simple regarding delay and phase: subwoofer at the front, between the speakers, phase at 0°, and done. Curiosity got the better of me, so I connected a hardware DSP to a secondary system (desktop, near-field setup) specifically to enable independent delay adjustment for...

At some point, most of us have bought into something that was supposed to be a game changer only to realize later the improvement was subtle, system dependent, or maybe not there at all. Other times, a smaller or less hyped change ends up making a bigger impact than expected. So I’m interested...

I released a new tool yesterday and wanted to share it here: https://github.com/ObsessiveCompulsiveAudiophile/GSonic GSonic Reference is a cross-platform room/speaker correction tool for stereo systems. It includes built-in measurement capability and generates convolution filters (FIR) that...

Hi everybody, I'm into the project of extending the use of room correction DSP, that I've been using for years for home theater to stereo listening (Roon and maybe also CD). So I know how to use REW, not to its full extent, but I know how to take measures with the Umik-1 and have a basic...

I developed a high-resolution AutoEQ optimizer designed specifically for Poweramp parametric EQ. Unlike magnitude-only fitting approaches, this tool simulates real parametric biquad filters and jointly optimizes gain, center frequency, and Q using robust loss functions and perceptual weighting...

Hi - I’m selling a MiniDSP 2x4HD. It’s essentially new in the box. I opened it up, registered, and then promptly put it on my pile of stuff to do later. I’ve since decided I no longer need it. What’s included: The DSP, it’s remote and it’s PSU w/ the North American adapter (I do not have the...

Hello everyone! Although I’ve been lurking around this forum for years, this is my first post here. I'm really sad that this has to be my first thread, but I need some help in case anyone knows. I have a Neumann system consisting of a pair of KH120 and a KH750 subwoofer. The connection between...

I've been trying many different desktop speakers and am not satisfied with any of them, so I came up with an unusual design. Attached is a crude diagram, not at all to scale, but it illustrates the idea. I want to achieve the following - flat response from at least 40hz to 17khz with little...

Forward–backward IIR filtering appears to offer zero-phase behavior with much less pre-ringing than linear-phase FIR EQs. This almost sounds like a “free lunch” what am I missing? Where are the hidden compromises compared to FIR?

Hi ASR! Real-Time GPU Power for Your Audio: Introducing a New GPU DSP/DDC Project I’m thrilled to share my project I’ve been developing that brings massive GPU computing power into the real-time audio signal path. The concept is a high-performance GPU-based DSP/DDC engine designed to redefine...

For a specific need requiring free signal re-routing, I identified and purchased the Nuprime-X H16-Aip, which arrived on October 31st. I believe I am the first user in my region. The H16-Aip addresses AoIP system decoding needs at approximately one-third of the budget, offering significant value...

hello everyone, i need a 4 channel dsp to put between the pre amplifier and the speakers, better if balanced , what product did you use? i need atleast 15 parametric filters. there are plenty of option and i dont know which one to chose, it has to have in and out soo i can use it between

Hey there, I'm currently considering buying a Neumann KH 750 DSP for my Small Studio, but I just don't seem be able to find any actual reviews with measurements eg, frequency curve, THD, Decay and so on. How is it that there is no review with measurements on such a respectable Brand's newest...

Hello everyone,in this video: I got a BDSP2.4U DSP processor for review, based on the adau1701 chip with two inputs and four outputs. Thanks to Sigma studio,you can make many corrections and changes to the audio signal,adjust the delay,signal level,equalization, crossover and much more...

Hey ASR! I am currently working on a rather ambitious project, but so far progress is steady and very promissing. I am trying to build an active crossover with 8 analog outputs to power a set of 4 way active speakers. For now, this is what it looks like(still a work in progress): The goal is...

I have been thinking about measuring and EQing my Beyerdynamics DT 900 Pro X and ZiiGaat Nuo with REW. Does this translate to noticable real-world benefits?

Hi All, I've only discovered this awesome forum earlier in the year, it has been great fun reading through all the detailed reviews and forum discussions. My background is in car audio (many years ago), which is probably why I am asking this question. About 6 months ago, I started researching...

Roon (bitperfect) 16/24 Bit sources | RME Digiface Dante ( accepts 24 Bits at Input) ( probably 32/64 Floating point internally) | Audioström Live Professor (Plug in Host) | Plug in with 40 Bit Floating point ( shaped dither 16- 24 Bit or Off)...

I have a WiiM Mini and am enjoying the EQ functions and I plan to try the room correction. I am so new to DSP that I’m not sure how to ask this (what the components are called) but is there such a thing as a DSP unit for home use that goes before the integrated amp input and has tools (maybe in...

For your opinion, is it necessary to have the AUTOMATICALLY changing of the convolution filters in accordance with the changes in the sample rate of the reproduced material? @digitalfrost @Soniclife @somebodyelse @terryforsythe
