LDT Online: Audacity

Christopher Christopher Hernandez earned this badge on Mar 22, 2019

Audacity is an open source software program that is used to record, edit, convert, and listen to digital audio files. 


Challenges

  • Audacity as a tool

    Reflect on the various ways that Audacity could be used in educational, training, or personal learning environments. From your selected perspective, describe two different examples where Audacity could be integrated and used. In both cases, explain why Audacity could positively impact learning.

    Use the open text area to submit your reflective response. As a suggestion, you may want to first compose your response in a word processed document, check for all editing that needs to be completed, save your response so that you can access it later, if needed, and then copy and paste your response in the open text area for this challenge.

    Audacity is a free, open source tool that can be used in educational and training environments.

    Audacity, at its core, is a cross platform editing software. The software allows users to perform a variety of different tasks. Users can edit audio by snipping out unwanted sounds and silence from clips. The software also provides users with the ability to add effects to audio which range from amplification of sound to noise reduction and crossfades. Additionally, Audacity can record sound as well, allowing users the ability to create audio for a variety of uses.

    Educators can find several uses within the Audacity software. Students who want to learn about digital music production and editing can be tasked in starting with this program. Educators will be able to teach the basic editing skills required for digital audio production. This would provide students with hands on experience in audio editing. Audacity could also be used to create educational podcasts as well. Educators have the ability to continue education outside of the classroom by using podcasting as a tool to continue the conversation. This can positively impact learning by allowing educators to expand upon subjects that they do not have the time for in school.

    Audacity can also be used to record voice over narrations for trainings. Providing pre-recorded narration is useful for both the instructional designer and the learner. The instructional designer can record their strongest talking points in the form of narration for both training films and presentations. These audio clips can also be used for pre-recorded online trainings. This impacts learning in a positive manner by allowing educators to engage learners in a consistent and concise manner.

  • Using Audacity

    Step-by-step instructions for this challenge

    1. Review these Audacity tutorials:​
    2. Go to the Audacity homepage and download Audacity.
    3. Complete each of the following*:
      • Record a track -- Record a track into Audacity using your microphone. This track can be an introduction to the rest of your audio file.
      • Import tracks -- Import at least 2 audio tracks (MP3, WAV, FLAC files, etc.) into your project.
      • Trim -- Trim at least one of your audio tracks down so that only a portion of the original track will be included in your final audio file. Take screenshots of this track before and after trimming.
      • Volume -- Adjust the volume level of each of your tracks so that no undesired leaps in the volume level occur between tracks.
      • Fade In/Out -- Fade at least one of your tracks in or out.
      • Other Effects -- Apply at least two other effects to your audio file (tempo change, vocal removal, reverb, etc.).
      • Export your project as an MP3.

      • In the open text area, write a short explanation of your track that explains each of the edits you made, including the two "other effects" used in the creation of your audio file.

      • Submit your work.
        1. Attach your two screenshots as files to this challenge.
        2. For the audio file, you will need to submit a link to where the file is stored.  To store the file and get a link, do one of the following:
          • If you have a course ePortfolio, create a sub-page and label it "Audacity."  Upload your MP3 file to this page. Submit a link to that sub-page.  
          • If you do not have an ePortfolio, you can easily use Google Drive to upload the file and share the link to the file from there.
          • Finally, if all else fails, make a copy of your audio file on a flash drive and submit it to your teaching assistant.

    * This list of tasks was adapted from the work of R. West, D. Randall (2014) and their colleagues at Brigham Young University (iptedtec.org).  Permission was granted for the use of this list of tasks.

    Criteria for successful completion of this challenge

    • All deliverables have been conscientiously uploaded and are fully accessible by the grader.
    • Completed audio file displays artfulness and professionalism through the following:
      • High recording quality for original recorded section​ (not scratchy or muffled).
      • Smooth and articulate vocal narration in original recorded section.
      • If there are breaks between tracks, these have smooth transitions.
      • If tracks are layered, there is artful layering of tracks (tracks don't distract from each other).
      • There is coherence to and evident care taken in the selection of tracks combined in this file.

    Deliverables for this challenge

    1.  1 link to a mp3 audio file created on Audacity, combining/using:
      • 1 original voice recording 
      • 2 imported audio tracks, with at least one track 'trimmed' from its original length
      • At least 3 separate effects, including a mandatory fade-in or fade-out effect
    2. screenshots of one of your audio tracks 'before' and 'after' applying the trim function.

    For this challenge, I've recreated my podcast intro with the addition of a small explanation. All three tracks have effects added on to them.

    Track 1's Bass & Treble have been increased and the levels have been lowered. I also performed a noise reduction on this track.

    Track 2 also has increased bass & treble with lowered levels. It also has a fade in and fade out at the end of the track. Finally, the 2nd track has also been normalized.

    Track 3 has the same bass, treble, level edits with a fade in on the beginning of the track.

    The screenshots show the editing down of the main imported track and follow the progression of editing and effect adding.
