Sandwich Builder

Sandwich Builder is a "gamified" tool for assessing auditory short-term memory span.

Sandwich Builder, and its digital materials, were created/drawn by Dr. Drew J. McLaughlin. Please cite McLaughlin and Samuel (2025) if you re-use any part of the experiment or art. Most of the materials are available on OSF: https://osf.io/snmqt/files/osfstorage. Requests for additional materials should be addressed to d.mclaughlin@bcbl.eu.

Base64 to WAV Converter

In online experiments, audio recordings are sometimes stored as Base64-encoded strings within CSV or Excel files rather than as standard audio files. Extracting and converting these recordings into usable formats can be time-consuming when done manually. To address this issue, we developed an R script that automatically extracts Base64-encoded audio data from CSV files, decodes it, and converts it into WAV files using ffmpeg. This tool allows researchers to batch-process recordings efficiently and reduces the time and effort required to prepare audio data for further analysis.

R script available in GitHub: https://github.com/bwwwl/Base64-audio-decoder

Users may need to adjust the row or column indices depending on where the Base64 strings are located in their data files. If you have any questions, please contact Brian Wong at brianwong0513@gmail.com

Clickety Split: Audio Segmentation for Speech Experiments

Interactive recording segmentation tool for speech perception experiments. Detects word boundaries in recordings using VAD + acoustic analysis, lets you review and adjust in-browser, then exports individual tokens as WAV files.
