Position ID: AXG-1182 JOB DESCRIPTION: Career opportunity for an experienced Audio DSP Software Engineer who will develop and maintain digital mixing software plug-ins that implement audio signal processing on a variety of hardware platforms. The plug-ins consist of high-level user interface code, low-level hardware sub-system control, and low-level signal processing code running on Mot...

Hello! In order to quantify the broadband noise of an audio track, how about implementing an adaptive filter? Does anyone know how can I proceed (matlab or c ++)? I've seen lots of things around and it seems the only viable option to estimate the broadband noise. Thank you in advance. --------------------------------------- Posted through http://www.DSPRelated.com

Hello list, I am a young student attending a Master in Computer Engineering focused on Audio Engineering and Sound Design. I really like the topics I'm studying and I've read some articles from the Journal of the Audio Engineering Society. Now I think that getting hold of the AES electronic library could be really valuable. My University won't buy it, and new it's too expensive. So even if I...

Hi all, does anyone know about any freely available library in C++ to obtain mp3 data stream? I am working for a project on audio classification and mp3 data is stream is required. I am working on windows platform. Regards Yoshita nanda This message was sent using the Comp.DSP web interface on www.DSPRelated.com

Hi I am carrying out some research work into the viability of automatic conversion of audio (various formats) into a range of codecs. It needs to be able to produce professional quality conversions using a range of (user definied) sampling rates. I would like to talk to people or companies who carry out this type of work and who can integrate this type of software with third party har...

Greetings I hope I'm in the right place, and forgive me if I appear dumb! I need to do Fourier Transform analysis of some audio impulse response files, for a Uni assignment (Music Engineering). I have been recommended to use Matlab for this, and as my Uni has it, I have gained access... however I do not really know how to operate the program, and unfortunately I don't have time to start ...

I'm probably asking you very stupid question, but i'm totally new to the field of Audio processing/analysis. I have recording of someone talking and I need to compute few basic characteristics for audio features: amplitude, phase, intensity. How do I start with it? If you know any useful online resources, please let me know. I'm using matlab a lot, if you have any library functions that do thi...

I've released the pksampler and pkaudio packages. PKAudio is an audio lib/daemon that makes asynchronous communication with a realtime audio engine from high-level languages like python easy. It is incredibly simple to write extension modules (subclass, implement two simple methods, link with executable), and is a very nice place to start for someone looking to get right to the importa...

I want to design a real time, multiband gate for audio signals, all in software (as a VST module). I thought it would be relatively simple but both the problem itself and the results of my experiments (through my headphones) are making my ears bleed. So I have a number of questions. My initial thought was to use an FFT to split up the audio, apply the gate effects, and take the inverse. FF...

Sorry for bothering you with the question that you probably heard a hundred times... I'm new to DSPs and would like to buy a DSP starter kit to learn. I'd like to have some practical results from this work, so I aim to develop an audio processing unit taking stereo audio signal from CD, upsampling it, applying some filters and putting it out through high sample rate DACs (192 kHz, 5 channels wo...

I am trying to write a program for Windows that does realtime audio processing from the MIC input and pushes the result to the speakers. Essentialy, a guitar effect software. I need some sequential algorithms for Auto-Wah, Reverb and similar effects because my project is to try to parallelize these algorithms in order to lower CPU Usage. Can anyone provide me with some sample codes, or links? ...

Dear all, I am working on a project that involves transmitting music through GSM phones. Since the GSM audio codec is designed for speech and not music or general audio, the quality is quite bad. I realise that this will always be a problem, but I was wondering whether there are ways to preprocess the music in order to reduce the amount of distortion. One of the things I considered was t...

Hi, While working for audio systems builder, I've been witnessing DSP work slowly disappearing. We are no longer developing audio algorithms as we used to. The optimization work is disappearing too. Either we buy DSP with software and use it as a black box or we simply use the already optimized DSP library. The work that's left for us is the integration and the test. How is it for the w...

Hi all, I'm writing a driver to allow me to communicate from my C6711 to the TLV320AIC23EVM Audio Codec. This communication involves writing the control registers via mcbsp1 and streaming the audio data via mcbsp0. I'm currently trying to write to the control registers on the codec but I'm not sure if I'm doing it right. I have jumped JP1 on my DSP board to connect mcbsp0 to the AIC23 daug...

Hi all, I have found an algorithm that filters an audio signal. The algorithm uses LP1 filters and produces exactly what I need. The problem is that the algorithm I found works at 44100Hz, and for my needs it's too much, I would like to save some CPU cycles and convert it to 22025Hz or 11025Hz. If I downsample the input audio signal and I run the algorithm unmodified, I do not get the des...

Just an observation: the largest part of a modern computer game is the library of the miscellaneous sound samples. Announcements, dialogs, nature, music, etc. Isn't it strange that the video part of a game is produced by the real time rendering of some kind of a simple model of the reality, whereas the audio is stored as the samples of the live sounds? Why the fairly sophisticate...
