Grenoble, France, August 12, 2011 -- The sound quality of an audio application can generally not be heard before the availability of a demonstration board. Dolphin Integration enable to bypass this hurdle by providing the functionality enabling to import and export audio files from its mixed-signal simulator SMASH, without having to develop dedicated modules to read and write .wav files!
Indeed, SMASH enables designers to generate audio output files (.wav) from the results of a time domain simulation for listening to the effects of an audio application during the design phase.
SMASH also provides the ability to transform an audio file into a dedicated voltage or current source model. This model serves as input to the analog model of any audio function for performing a transient simulation.
Moreover, it is possible to select the interpolation method applied to it in order to prevent simulation discontinuity issues. “This feature is very useful when we want either to listen to the impact of different design solutions on audio quality (e.g. Pop-up Noise) or to simulate designs with more realistic signals than just sine waves based signals.” said Sebastien Genevey, Engineering Manager of Audio Codec development at Dolphin Integration. “It is also suitable to check the equivalence between the final implementation of our new Audio Signal Processing functions and their initial high level model.”
For Japanese readers, both uses of SMASH are described in the article “SMASH AUDIO APPLICATION” written by Takahiro Yanagi, PI research LABO.
Download SMASH at the following link http://www.dolphin.fr/medal/smash/smash_download.php and try out now the import/export of .wav files.
A tutorial called “Audio Files Application” is even provided with the Discovery option to ease your acquaintance!
