 +A dataset for evaluating the work on microphone signal processing chain was collected and can be found here: [[https://​drive.google.com/​open?​id=0B1dik9fZbclrNHBsTVZFVUFRNFk|dataset]]. This dataset is a set of recordings for two speakers for two different types of microphones for different usecases. More detailed info can be found in the readme file inside the dataset folder.

 +In order to better understand mixxx engine and mixxx native effects, a [[https://​github.com/​mixxxdj/​mixxx/​pull/​1284|utility effect]] was developed and an accompanying article in the wiki was started demonstrating a practical way on how an native effect can be developed. [[https://​mixxx.org/​wiki/​doku.php/​effect_development_example | Mixxx Effect Development Example]] 
 +     
 +Also a minimal framework have been developed in python for prototyping and tuning audio dsp algorithms in python with numpy and other existing python packages such as adaptfilt and speexdsp-python. The pull request can be found [[https://​github.com/​mixxxdj/​mixxx/​pull/​1290 | here]] 
 + 
 +The framework supports both file input/​output and realtime audio processing. For the realtime audio capabilities it requires sounddevice which requires portaudio. 
 + 
 + 
 +Currently I am porting CAPS [[http://​quitte.de/​dsp/​caps.html#​Noisegate|noise gate]] algorithm as a native mixxx effect in order to gain more experience with mixxx engine.

 +== week 4-5 == 
 + 
 +Plan for the next two weeks is to have the noise gate implemented,​ and have decided on and implemented a microphone effect rack (help needed here) that will later be the place in the skin for setting up microphone effects, and other microphone related settings and possibly be selectively routed to the main effects rack.
