- Two 17-inch Intel Core Duo iMacs, 1.83GHz, 1GB ram each.
- Two MOTU Ultralight external audio interfaces for recording and playback
- Sound Studio 3 audio recording software
- Sony MDR-7506 Studio Monitor Headphones
- Presonus Headphone Amp
- 19-inch Acer widescreen monitor in the recording booth for presenting visuals to the subject
- Marantz PMD 670 flash recorder with a firewire card reader for transferring sound files from PMD 670 to disk
- 1 AKG C420 headset microphones
- Stereo-to-XLR converter for "TriggerWave" application
Swift 228: Speech Perception Lab
- The Swift 228 collection of computers consists of 5 experiment-running computers in individual booths, arranged as follows:
| Dakota |
|
|
Machine Room/
Closet |
|
Recording Booth |
| English |
| Hausa |
|
|
| Basque |
Afrikaans |
- Software on these computers includes MS Office 2003 Small Business Edition, Statview, Endnote, SuperlabPro, and Praat.
- All five booth computers have Superlab button boxes and headphones that stay with them. If you are using the Superlab button boxes, you can use the colored key caps. These are stored in the box labeled "Superlab Keycap Kits" in the topmost cabinet opposite the booths.
- Additional headphones and microphones are in the cupboard in Swift 228 and in the bottom right cabinet opposite the booths.
Cresap 105: Production Lab
- Cresap 105 consists of large booth with recording, response pads, and stimulus presentation equipment located inside. External to the booth is Cylon, a dual-boot (OS 9/OS X) Mac G4 that controls stimulus presentation.
- Stimulus presentation equipment.
- 3 independently controlled flat-screen monitors
- Speakers
- Headphones
- MOTU Ultralight external audio interface
- Recording equipment
- 2 AKG C420 headset microphones
- MOTU FireWire Audio interface + 17-inch Intel Core Duo iMac, 1.83GHz, 1GB ram, for direct recording of multi-talker audio input (as well as TriggerWave signals from Cylon) to disk
- Glottograph (stored on top of the booth)
- Response pads
- Keyboard+Mouse
- 2 Superlab button boxes
- Superlab voice key
- For field recording, multiple mics + 2 PMD 670 flash recorders are stored on top of the cabinets on the north wall.
- Forms, including consent, debriefing, and receipt are stored in the cabinet on the south wall.
Cresap 101: Computing and Presentation Facilities
- Presentations: A ceiling mounted projector with screen, PC laptop and small speakers available for presentations. The remote control for the projector along with a dongle for hooking up Mac laptops is in the rightmost cabinet along the north wall of the room.
- Computing Facilities: Two old Mac computers are available for classroom demonstrations or sound analysis (Praat is installed on both). A new Mac (fisher) is also available; it is used primarily for web design, corpus/database analysis, and simulations.
Swift 310: Data Storage and Processing
The Swift 310 collection of computers consists of:
- Polyglot: a desktop computer whose main purposes are (1) speech database storage and (2) data processing using Matlab and various utilities for adding noise to and leveling stimuli. [NB: Polyglot is currently housed in Swift 228.]
- A portable perception testing setup including a laptop (Cantonese 2), with headphones
Cresap 115: Computing Facilities
The Cresap 115 collection of computers consists of:
- Dalek: a Mac G4 whose main purposes are (1) data storage (2) data processing (3) simulation (4) corpus/ database processing
- A firewire card reader for transferring sound files from PMD 670 to disk The desk under Dalek is for storage of SoundLab related consent and subject information forms (lower left hand drawer).
