Recording: At the moment to record the gestures and synchronize the Myo device with video and audio data, we implemented a Max/MSP program which sends OSC events to the Myo application to generate a database of CSV files, it records the data at 60 fps. These files are created taking into account a synchronization format: timer in milliseconds, accelerometer (x, y, z), gyroscope (x, y, z), Quaternion (w,x,y,z), electromyogram (eight values), point_vector(x,y,z), point_direction (x,y,z), point_velocity(x,y,z), event (it is a marker during recordings). Those CSV files are recorded in the same time-window range reference of the audio data, also created within Max. The format of the video, myo and audio files are defined by counter_gesture_second-minute-hour_day-month-year (extension are .csv, .mov or .wav), where the counter is the iteration of the recording session, the gesture is the identificator number and time/date description to pair all files and avoid overwriting. The master recorder in Max/MSP sends the global timer (ms) reference to the Myo application which is reported in the CSV file. To acquire audio we used an interface Zoom H5 linked to Max, recording WAV files with a sample rate of 44.100 Hz/16 bits. Myo device running in a MacBook Pro (13-inch, 2017), 2.5 GHz Intel Core i7 processor and a memory of 8 GB 2133 MHz LPDDR3 with a latency of 10ms to 15ms. However, the final alignment is controlled by the Openframeworks app. The sound file reader reports the millisecond where the audio is being read, then, that value is passed to the CSV reader with an offset of -10 (ms) giving the motion information to be visualized.
