Top tips for sharing audio files with learners

I use audio a lot in my work, both for giving learners feedback but also for the creation of learning objects. One way to use audio is for each week or topic of teaching to provide a short audio file to set the scene, to provoke thought or as a form of additional information for those that want to take the topic further (differentiation). Many people will use their VLE to house these audio files – and if we do this there are a few tips that we can apply to make this process easier for ourselves and the learners. The following video will explain some of these ideas, and the details are further explained below.

Using leading zeros when naming files

If we are producing a sequence of audio files (e.g. 1 per week) – if we name  the files:

  • Underwater Origami Week 1
  • Underwater Origami Week 2
  • Underwater Origami Week 3
  • ……
  • Underwater Origami Week 9
  • Underwater Origami Week 10
  • Underwater Origami Week 11

This is OK if you have less than 9 weeks in total, but if you have 10 or more weeks, what can happen is when the files are saved together in a folder either on a computer or an audio playing device (e.g. mp3 player/phone) – the order of them may be displayed alphabetically, and with the above scenario, this would look like:-

  • Underwater Origami Week 1
  • Underwater Origami Week 10
  • Underwater Origami Week 11
  • Underwater Origami Week 2
  • Underwater Origami Week 3
  • ……
  • Underwater Origami Week 9

So to avoid this, it makes sense to save the filename with leading zeros e.g.

  • Underwater Origami Week 01
  • Underwater Origami Week 02
  • Underwater Origami Week 03
  • ……
  • Underwater Origami Week 09
  • Underwater Origami Week 10
  • Underwater Origami Week 11

This way if the files are arranged alphabetically, they will remain in the correct order.

Use CamelCase rather than spaces

If we have spaces in our filenames, when these are displayed as web addresses the space is often replaced with a %20 – which then stops the filename from making sense, so I tend to avoid spaces. What I do instead is use CamelCase – this is where all the words are lowercase, but the first letter of each word is capitalised so that it stands out (and creates a bump – hence the name CamelCase). This makes it easier to read on the eye.

  • UnderwaterOrigamiWeek01

Adding meaning into the filename

With the example that I have used so far, this works if we know what is being covered in each week, but if a learner is coming back to this at a later date to revisit a topic that they are struggling with, or need for their assignment – if they don’t know which week each topic was taught in it can be frustrating trying to guess which file they want, so adding a brief description at the end of the filename will help e.g.

  • UnderwaterOrigamiWeek01-Introduction
  • UnderwaterOrigamiWeek02-TypesOfPaper
  • UnderwaterOrigamiWeek03-FoldingTechniques

Makes a lot more sense.

If using dates use yymmdd format

If you want to include a date in a filename – then use the yymmdd format, or reverse format – e.g. todays date is

9th July 2012

This would be recorded as the year first (12) then the month (07) then the date (09) to give a final date of 120709. The reason we use this is if the files are arranged alphabetically – if we have used this format they will also appear in the correct chronological order. e.g.

  • 120608UnderwaterOrigamiWeek01-Introduction
  • 120615UnderwaterOrigamiWeek02-TypesOfPaper
  • 120622UnderwaterOrigamiWeek03-FoldingTechniques

Zipping the audio files for easier downloading

If distributing the files each week via the VLE then that is great if the learners are diligent enough to access the VLE, to select the file and download it onto their audio player or computer. However it is worth considering as well as doing this, also putting all the files into a folder, zipping this up, and uploading this zip file as a file – this way the learners have the option of downloading the whole series in one go, rather than having to visit every link in turn and save etc.

If you are recording the files as you go along with the teaching, then this can be done at the end of each term for example for students to download retrospectively, or if the audio files have been produced in advance, then you have the choice of doing this at the beginning, so they have the files in advance.

Another important feature when using audio files is to use the metadata options – which will be covered in the next post….
