Finding and Using Audio

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.

Finding Audio

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

General Terms:

  • CODEC
    “A codec (a blend word derived from “coder-decoder”) is a program, algorithm, or device that encodes or decodes a data stream. A given codec knows how to handle a specific encoding or compression technology.” —Mozilla. “Codec.” MDN Web Docs Glossary.
    Learn more about audio codecs by reviewing Mozilla’s Web Audio Codec Guide.
  • Compression
    “A process that reduces the amount of space necessary for data to be stored or transmitted.” —Society of American Archivists. “Compression.”
    Dictionary of Archives Terminology.
  • Lossless
    “Lossless is used to describe digital compression techniques in which no information is lost; an object is identical before and after being compressed and restored.” —Society of American Archivists. “Lossless.” Dictionary of Archives Terminology.
  • 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. “
    Lossy.” Dictionary of Archives Terminology.

File Formats:

  • AAC: Lossy format
    Can be seen with the file extension .aac, .m4a, or .mp4, among others.
    “Advanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression. Designed to be the successor of the MP3 format, AAC generally achieves higher sound quality than MP3 encoders at the same bit rate.” —Wikipedia contributors. “Advanced Audio Coding.” Wikipedia, Accessed 20 Jun. 2023.
  • MP3: Lossy format
    Designed by the Motion Pictures Experts Group, the MP3 is a
    lossy audio compression file type. “The MP3 lossy audio-data compression algorithm takes advantage of a perceptual limitation of human hearing called auditory masking.” —”MP3.” Wikipedia, Accessed 20 Jun. 2023.
  • OGG: Lossy format
    “Ogg Vorbis is a fully open, non-proprietary, patent-and-royalty-free, general-purpose compressed audio format for mid to high quality (8kHz-48.0kHz, 16+ bit, polyphonic) audio and music at fixed and variable bitrates from 16 to 128 kbps/channel. —”Vorbis audio compression.” Xiph.org.
  • 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

Using Audio

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.
