Abstract
Methods and systems of authoring audio signal(s) into haptic data file(s) are disclosed. An audio analysis module analyses the audio signal(s) using filterbank(s) or by performing a spectrogram analysis. Transients are detected in the audio signal. If present, the transients are processed to determine a transient score and a transient binary. A database stores device specific information and actuator specific information. A haptic perceptual bandwidth of an electronic computing device having an embedded actuator is determined by using information from the database. A user interface allows modification of time-amplitude values and transient values based on the determined haptic perceptual bandwidth. Authored time amplitude values are aggregated in authored audio descriptor data, which is passed to a transformation module that fits the data into the haptic perceptual bandwidth and implements algorithms to produce transformed audio descriptor data. Finally, the transformed audio descriptor data is converted to the haptic data file.
