Academic Audio Use
Audio can play an important role in scholarly research—and not just in the field of music! Sound recordings can serve as evidence, inspiration, data, or the soundtrack for a creative project.
For more information about copyright’s impact on media use, contact Paula Kiser.
For help with technical aspects of audio creation and editing, contact Senior Academic Technologist, Brandon Bucy.
The following sections outline the process of an effective audio search–a process that includes the identification of project need and the location of appropriate resources.
Identifying Your Need
Before you conduct your audio search, consider the following:
- What is the purpose of the audio within your project? Will it serve as evidence, primary source, focus of analysis/critique/commentary, or raw data for scientific analysis?
- What is your intended audience?
- What is the environment for your project (e.g., academic vs. creative project for public consumption)?
- What specific criteria should your audio meet (e.g., content, sound quality)?
- Are there discipline-specific conventions for audio use?
- What audio sources will you choose from (e.g., digital, analog, subscription databases, web, or personal creations)?
Pay attention to the following as you conduct your search:
- rights and restrictions of use associated with audio files
- textual information associated with in audio files (e.g., supporting text, user-generated tags, creator information, repository names, keywords, or other supporting information about the media file)

Understanding File Types
- CODEC: “A codec performs the encoding and decoding of the raw audio data while the data itself is stored in a specific audio file format.” —National Archives, Digital File Types
- Compression: “A process that reduces the amount of space necessary for data to be stored or transmitted.” —Society of American Archivists
- Lossless: “…digital compression techniques in which no information is lost; an object is identical before and after being compressed and restored.” —Society of American Archivists
- Lossy: “…digital compression techniques in which information is lost; an object is altered after being compressed and restored. Lossy compression sacrifices fidelity for size; fidelity and compressed file size are inversely proportional. The technique may be used in instances where the loss of information is not noticeable or significant.” —Society of American Archivists
- AAC: “Similar to the MP3, AAC files are compressed and maintain high quality. AAC is currently the standard format for iOS and iTunes audio files.” —Penn Libraries
- MP3: MP3 is an open standard developed by the Moving Pictures Experts Group that is highly compressed and removes data inaudible to the human ear (through a process called perceptual encoding).
- M4A/M4P (MPEG 4 Audio): MP4 is a audio file format that frequently utilizes lossy AAC encoding.
- OGG: “Ogg Vorbis (http://www.vorbis.com”) is a high-quality, patent-free, open source, compressed audio format and streaming technology.”—Bruce Fries & Marty Fries, Digital Audio Essentials
- WAV/AIFF: “Though the WAV and AIFF were originally designed for Windows and Mac platforms respectively, each format is now compatilble with both platforms. Both formats are uncompressed, very high quality audio, and are best suited for short, downloadable clips because of their large file sizes.” — Penn Libraries
- WMA (Windows Media Audio): “A proprietary compressed audio format developed by Microsoft and used by its Windows Media Player program.”— Bruce Fries & Marty Fries, Digital Audio Essentials

Once you have found appropriate audio sources, you still may need to alter them to fit your project. Just remember, as with any other data, avoid altering content in a way that may be misleading or misrepresent the original source.
Audio Editing Software

Creating Your Own Audio
Just as when evaluating pre-created audio content, creating audio files requires consideration of need, quality, and appropriate file type. There are many resources to help you make these important decisions, including a wide selection of Safari Technical Books.
