Basics of Digital Audio-Frequency = speed, measured in Hertz (Hz)-Volume = level, measured in decibels (db)-Sample rate is the number of samples recorded per second-measured in Hz or kHz. A CD has a rate of 44,100 Hz.-Sample size or format is the number of digits in digital representation of sample. Measured in bits, a CD is 16 bits. The higher the sample size the more dynamic range-louder louds and softer softs. Measured in bits-16 bits being standard for CD quality.
File Formats• Most common types of file formats:
AIFF, WAV, MP3, Ogg Vorbis, AAC & WMA-Uncompressed and high quality-AIFF, WAV-Compressed but small file size - MP3, Ogg
Vorbis-MPEG4 or AAC (Apple) and WMA (Windows)
are proprietary and not supported by Audacity.

Recording Basics
• Microphone-Computer-Audacity• Skype for out-of-town subjects • Low Cost recording setupsInternational Association of Internet Broadcastershttp://www.ibroadcastnetwork.org/blog/best-dynamic-microphones-under-100-dollars
Recording Basics
• Best settings for recording -Microphone!-For multiple speakers, more than one
microphone should be plugged into a mixer that then gets plugged into computer.
-Recording room tone to mask any silent spots or use as a “noise print” to take out hum or background noise.
Using Audacity
• Settings• Importing Files• Cutting and placing clips• Adding tracks as bins• Setting the volume• Tools• Saving project/Exporting File
Using Audacity
• Cleaning up pops, background noise, and “ums” and coughs.
• Normalizing Audio• Loudest part of your recording should approach
0db on a VU meter, anything above will distort. • Creating files for different applications. • The importance of keeping high resolution master
files.
