Hello I have two DSP connected in serial mode. Have FIR with 2000 coefficients . Need to recalc and divide coefficients of FIR by 1000 for 2 DSP, so that in serial application give result of FIR with 2000 points. Delay of FIR here dont work, bcs FIR of each DSP is 1000 points maximum. Is this possible? WBR, Vasilius. --------------------------------------- Posted through http://...

The church I belong to is planning a website which will include recorded sermons. The proposal for site design and hosting did not explicitly mention how much online storage was included. A brief search told me a minute of MP3 occupied ~1 MB. No mention of fidelity. I assume that would be satisfactory for speech. What if they wanted to record choral music. I know essentially nothing a...

I have come across other derivations that seem more laborious. Now unfortunately, the author has made the equations as GIFs with very small

I guess you can train this thing up on an error correction code as well: https://groups.google.com/forum/#!topic/comp.ai.neural-nets/A_XqO9ehjDk

Hitting a little bit of a wall doing some sinusoid tracking and in an effort to work smarter not harder, I'd like to do some hanging out with someone experienced in MIR. Neural net knowledge a definite plus. This is a pretty fun project so hopefully it won't be too painful. Rates negotiable. Matt EstateSound Com


Anatomy of a reverb algorithm

I know that reverbs are normally built with all-pass and/or comb filters in various combinations. Are there topologies that are more CPU-efficient, or more realistic? I'm interested in small room emulation, but I need to keep up in real-time, and processing power may be limited. Obviously many common algorithms are just refinements of the the old Schroder algorithm, but that's a primitiv...

First post! Advance apologies for newb-ness. I've made a quick implementation of Orfanidis 'decramped' prescribed nyquist gain peaking filters in C++. Seems okay but I would like to be able to specify... Peak gain in dB Peak frequency in Hz Peak Q say 0.1 to 4 rather than... (G0 = reference gain at DC = 1) G = boost/cut gain GB = bandwidth gain w0 = center frequency in rads/sam...

Hello, I am a Ph.D. student working on developing new objective measures for evaluation of source separation in music; in my lab we are conducting a listening experiment to evaluate the quality of separation of the singing voice from popular music. We are looking for volunteers to participate in the study and we would be grateful if you can help us out. If you choose to particip

I can't Google for this -- I just tried. Broadcast radio, and DirectLink satellite TV, have Really Expensive transmitters to serve lots and lots of cheap receivers, because it minimizes total system cost. "Old style" satellite TV had (fairly) inexpensive transmitters and (until people put them in their back yards) a few big expensive receivers (and antennas). Because -- it minimizes...
