The use of time selective techniques has been used for years in signal processing for acoustic, vibration and electro-acoustic to make simulated free-field measurements. Many acoustic solutions have been implemented and developed by specialized software companies and are offered to final users by the costs of large amounts of money. However, recent advances in hardware, software and data acquisition systems - allied to a good background in signal processing - has enabled the implementation of fast and practical solutions to more complex problems involving direct signal manipulations, analysis and post-processing.
