Below is a USB setting we discovered during the second workshop.
USB and Power Settings
The USB Connection setting needs to be changed to either connect the recorder to a computer or to power the recorder from AC while recording. There are 3 options:
- PC: allows the recorder to be connected to a computer. Can be used to charge the batteries.
- AC Adapter: allows the recorder to be in record mode while connected to AC. Can be used to charge the batteries.
- Optional: anytime the recorder is connected to a computer or the AC Adaptor it will display a menu to select PC or AC Adapter. Use this setting.
- Press the MENU button
- Forward through the tabs to the DEVICE MENU
- Press the - button down to select USB Settings and press OK.
- Select USB Connection and press OK.
- Select Optional and press OK.
- While playing an audio file the speed can be changed from 50% to 400%.
- During playback the up and down arrow button on the front right of the recorder adjust the playback speed.
- Leave it set to 100%.
- If the playback speed was set to 90% the recording would sound close to normal but it might have a weird sound. This could have been the cause of the weird modulations some of you heard while playing files during the workshop.
Audacity is developed by a team of volunteers and released under an open-source license and is the only audio editing software that is run on Mac's, PC's, and Linux computers. Go to http://audacity.sourceforge.net/ to download the most current version, 2.0.5.
Open Audacity found in the applications folder.
Save your project
(preferrably after every edit) File > Save navigate to your hard drive and create a folder with your name and save it to that folder. This folder will contain all your audio files and edit information so you can continue to work on different computers so keep this folder and it's information contained.
Inside your folder there will be the Audacity project file with a .aup extension and a folder ending with _data.
For example, inside the folder called interview if the project was named October there would be a file called October.aup and a folder called October_data.
Always keep the project file and data folder together.
File > Import > Audio navigate to the audio files that you want to import.
If Audacity opens a warning screen click the option that says "Make a copy of the files before editing (Safer)" and click OK.
