real time audio processing tool in C++ -


i trying record , calculate spectrum in real time. wonder library should use purpose. need integrate original c++ code , combine image feature. looked opensmile , seems not suit purpose.

any suggestions appreciated!!

here pretty comparison , evaluation of various audio feature extraction toolboxes.

main conclusion based on paper mention in link below:

1) essentia: full function workflow environment high , low-level features, facilitating audio input, preprocessing , statistical analysis of output. written in c++, python binding , export data in yaml or json format.

2) marsyas: full real-time audio processing standalone framework data flow audio processing gui , cli. program includes low-level feature extraction tool built in c++, ability perform machine learning , synthesis within framework.the feature extraction aspects have been translated vamp plugin format

3)yaafe low level feature extraction library designed computational efficiency , batch processing utilizing data flow graphs, written in c++ cli , bindings python , matlab

you can find more details graph of percentage coverage of multiple feature sets , graph of computational time of feature extraction tools in link.

ruby on rails - Seeing duplicate requests handled with Unicorn -

recently upgraded our ec2 instances c3.large in order boost more unicorn workers handle increased traffic our site. (6xworkers per machine - 2 ec2 instances). when did this, started seeing duplicate records being created! looks somehow, maybe 2 unicorn workers attempting process same request? in nginx logs see 1 [post] request particular rails controller - yet 2 records being created in database. i'm hitting kind of race condition issue - have no idea how debug this. doesn't happen time, when it's frustrating well. noticed 2 database records within 5 seconds of each other. (and yes disable button when user clicks submit button). unicorn 4.8.2 ruby 1.9.3 rails 3.2.14 any great! thanks! although may not fix problem, upgrade ruby 2.0.0. there blog mentioning idea upgrade ruby 2.0.0 if using unicorn. for example: https://www.digitalocean.com/community/articles/how-to-optimize-unicorn-workers-in-a-ruby-on-rails-app specifically: if using ruby 1.9,
