LetsWave is an EEG signal-processing toolbox written in Borland Delphi 7 and running under Microsoft Windows. It was developped to perform fast multi-subject analyses of event-related potentials with specific focus on time-frequency analysis methods using the Wavelet transform. Letswave is composed of a multitude of signal-processing 'modules' which are all controlled through a single user-interface. Time-frequency decomposition is performed using an optimized Morlet wavelet transform algorithm. Besides time-frequency decomposition, several modules allow the processing of EEG either in the time, the frequency, or the time-frequency domain. Furthermore, several statistical modules allow comparing results across multiple conditions.
