Research File System (RFS) account:

At IU all faculty members and graduate students are eligible to apply for a RFS account, which gives you 10GB of storage space. This extra space would be very helpful to save large sound files. The files on the RFS are accessible on every computer on campus.

To apply for a RFS account:

1.      Go to http://itaccounts.iu.edu

2.      Click on “Manage my IU computing accounts

3.      On the left panel, click on “Create more accounts”

4.      Select “RFS” to create.

5.      If you don’t see the option of RFS, then send an email to valid@indiana.edu . The staff of UITS will manually create a RFS account for you. In the email be sure to mention that you are a graduate student or staff member and also give your IU network ID.

To access your RFS account:

  For Windows:

1.      Right click on “My Computer” icon on the desktop.

2.      Select “Map network drive”

3.     In “Folder”, type \\rfs.iu.edu\username (replace ‘username’ with yours) and then click “Finish”. Assign a label to your RFS drive other than W, which already exist on the PC machines in the lab.

4.      A dialog box asking for your IU network ID and password may pop up, just type in yours as usual.

5.      Your RFS account then should be accessible and could be seen in My Computer.

 

  For Mac OS X: (The instructions can be found at https://servicenow.iu.edu/kb)

  1. In the Finder, from the Go menu, select Connect to Server.
  2. In the Connect to Server window, in the "Address:" field, type: smb://rfs.iu.edu/username

Replace username with your username. Click Connect.

  1. You will be asked to authenticate. In the Workgroup/Domain field, type ADS. Type your username and password in the appropriate boxes.
  2. Click OK. Your RFS folder will be mounted on the local drive shortly and can be seen under shared space.

Recording (Recording can be done in LAIKA and Mac workstations.)

Before recording, make sure that the microphone is plugged into the EDIROL sound capture device, and the USB cable is connected from the sound card to the workstation you are working on.

For recording under PC:

  1. Open Adobe Audition 3 from Programs.
  2. On the bottom panel, click the red recording button in “Transport” tab.
  3. Specify the sampling rate for your recording. The default setting is 44100Hz, which is enough for most cases.
  4. Specify “Mono” for channels and 24-bit for resolution.
  5. Click “OK” to start recording.
  6. Click the square stop button in “Transport” tab to stop recording.
  7. The current file should appear on the left panel.
  8. To save the file, click once on the file name and then click on File from the command bar.
  9. Select “Save as” to save the current file to the designated directory.

Also, Wavesurfer is a nice tool to record:

  1. Open Wavesurfer from Desktop
  2. Follow the path: File àPreferences à Sound I/O to change the settings for sound recording. Make sure the input device is set as EDIROL UA-25 microphone.
  3. In most cases, set sampling rate as 44100Hz, encoding resolution as Lin16, and mono channel.
  4. Click Apply and Ok to save settings.
  5. On the main panel, click the red circle Record button to start recording
  6. Click the square black button to stop recording.

Alternatively, you can record using Praat in both PC and Mac

  1. Before recording, make sure that the sound input device is specified to EDIROL UA-25 by checking the Sound settings in Control Panel. If not, select EDIROL and set it as default.
  2. Open Praat from quick launch bar
  3. Click on “New” and then select “Record mono sound”
  4. Specify the sampling rate for your recording. The default setting is 44100Hz, which is enough for most cases. On Mac there is one additional setting of sound source—select EDIROL UA-25.
  5. Click “Record” to start recording.
  6. Click “Stop” to stop recording.
  7. Click “Save to list” to get ready to open the file.
  8. In Praat objects, you should be able to find the file you just recorded.
  9. Click on the file and select “Edit” to view the spectrogram and waveform.
  10. Click “write to wav file” to save it in the location you desire.

Monitoring subject's performance

  In case you need to monitor your subject's performance while they are recorded in the booth, you may use the headphone that is plugged into the EDIROL sound capture device. If you need to talk to your subjects during recording, you may use the microphone attached to the headphone that is plugged into the COMPUTER so that subjects can hear you.  Briefly, to hear what subject is saying, use the headphone connected to the EDIROL sound card. To talk to your subject, use the headphone with mic connected to the COMPUTER.

To scan a document:

  1. Turn on the scanner (the switch is located on the back of the machine.)
  2. open “Adobe Acrobat Pro 9” from “Programs”
  3. Select Create PDF à from Scanner à Custom scan
  4. Change the resolution and image quality as desired. If you are scanning a paper with more than 5 pages, limit the resolution up to 400dpi; otherwise, the output file will be too large to transmit.
  5. After scanning the first page, a dialog box will appear and ask you if you want to scan more pages. You may simply ignore this step and select “scanning complete” for now.
  6. To scan more pages, follow step 3 and make sure that the current page will be appended to the file you just created by checking the box “Append to….”

To scan an image:

  1. Turn on the scanner.
  2. Open HP Photosmart Essentials from Programs or Desktop
  3. On the left panel, click “Get images” and then select “from scanner” àselect HP Scanjet G3010àOK

  5. If the preview looks good, then click “Accept” to perform a final scan.
  6. On the left bottom panel, you may change the file name in “image information”
  7. The scanned image will be automatically saved in “My Scans” under Documents.

E-Prime

  1. If you need to use E-Prime, please inform either the lab director or assistant in advance to get the license key (a hardware USB type plug-in key needed to program a script in E-prime).
  2. Before scripting in E-Prime, be sure to plug in the license key to one of the USB ports. Otherwise, E-Prime won’t allow you to create or modify any experiments!
  3. To create or modify an experiment, open E-Studio.
  4. To run an existing experiment, open E-Run. (E-run can be operated without the license key).
