How do I ...?
Make a recording
Check availability and book booth in Sound Room via CBU Homepage Administration: it works with Internet Explorer.
Check availability of recording equipment: email Sally Butterfield
FlashcardRecorders: Flash Card recorders record audio directly to a Compact Flash card which can then be read directly into a desktop computer using either a cable or the flash card reader/writer. The basic recording function is very straight-forward, but the naming of files transferred, erasing and re-numbering tracks less so - consult manual or ask. Various formats and sampling rates are available: intermittent noise has occurred on some 22.05 kHz mono recordings. Best to check a sample before recording a long session or use 44.1 kHz and down-sample with sound editor.
Edit recordings
The first step is to install a waveform editor. The main one we use is Audacity, but you can also use its predecessor CoolEdit. Both programs can be downloaded from here: Audacity (local)
If you want to extract parts of a file (say individual words from a large file), or cross-splice or join files together, you should take a look at ProgramsToManipulateWavFiles. Note that these programs work best under Unix. You can save yourself a lot of effort by combining these programs in a Unix script.
Prepare speech and language experiments:
- EPrime
- DMDX
try looking in SoftwareTools
Use the testing booths in room 448
book a room for testing via CBU Homepage Administration: it works with Internet Explorer.
- keep the booths cool in the testing area. There is a sheet of suggestions on the wall.
- shut down at the end of testing day
report problems to Maarten van Casteren
Present sound in the scanner
