Working with sound

   


Audio material is regularly used when teaching speaking and listening in foreign languages. Therefore the teachers and the students should be able to edit and modify audio as well as texts.
Probably the best freeware available for editing sound is called AUDACITY.


Audacity Basics - you should be able to
- install Audacity and the lame library which enables export to mp3
- open a file in Audacity
- edit the file: cut and paste, fade in/out, change speed, delete, add silence
- create a new file
- combine two files (e.g. speech + background music)
- insert silence (e.g. as a space for an answer)
- change the speed or pitch (carefully!) to make understanding easier (or to have fun)


TASK 1 - WEB SEARCH
Choose an online audio resource - a podcast or TED you consider useful for an English teacher. Listen, and share the link and your opinion in the comments to this blog entry.

Inspiration/hint: What does the word "podcast" mean? Go to Podomatic, create an account and browse the site. How can we use it in teaching English?

EXTRAS
Sound files extensions:
wav -  Standard audio file container format used mainly in Windows PCs. Commonly used for storing uncompressed (PCM), CD-quality sound files, which means that they can be large in size—around 10 MB per minute. Wave files can also contain data encoded with a variety of (lossy) codecs to reduce the file size (for example the GSM or MP3 formats). Wav files use a RIFF structure

mp3 - compressed, MPEG Layer III Audio. Is the most common sound file format used today

flac - Free Lossless Audio Codec
ape - Monkey's Audio lossless audio compression format
ogg - A free, open source container format supporting a variety of formats, the most popular of which is the audio format Vorbis; compression similar to MP3

webm - Royalty-free format created for HTML5 video
aiff - Standard audio file format used by Apple. It could be considered the Apple equivalent of wav

Sluchové pole (nebo oblast slyšitelnosti) je rozsah všech zvuků, které dokáže lidské ucho vnímat. Vnímání zvuku je u člověka omezeno slyšitelnými frekvencemi (přibližně 16–20 000 Hz). U každé frekvence je odlišný rozdíl intenzit, jež slyšíme. Lidský sluchový orgán je nejcitlivější v oblasti frekvencí 1–5 kHz.

    This web page is really good for finding listening excercises on any level the students might be at. There is a broad spectrum of topics. The audio is usually in good quality and reasonably long. There are also comprehension questions included, as well as, pre and post listening excercises. You can also find the trascript to the audio, so it is easier for the teacher. The only problem is you cannot download the audio.

    I chose this TED talk because I find it very useful and relatable. It talks about the mind of a master procrastinator which I think we all are adn our generation is kind of notorious for tihs. We are used to complete assigned work right before the deadlines and not in advance.

    --- How to gain control of your free time ---

    I think this video is interesting due to being relevant in our daily basis. It could benefit both the adults and students with the question of spending their time effectively and with a goal, self-satisfaction. It is important when making choices to keep in mind that our time is our choice. By setting priorities, we divide our time knowingly. By making list of three categories a year ahead, we are more in control. Students will learn new vocabulary and maybe it would help their personal and educational growth. TED Talks has many interesting streams with relatable topics, you can switch on subtitles to English or different languages for better understanding for your listeners.

    Class is not primarily about information. More important is motivation and determination of our students.
    Use of short videos during our lectures can be an efective way to catch their attention.
    Less useless information can lead to more practice in class. Which is more usefull for our students.

    "The benefits of fostering beginner's mind"

    "Many of us typically disengage or even double down on our beliefs when we encounter opinions at odds with our own. Our biases tell us we have all the answers but, according to psychology grad Cecilia Guan, this mentality only stifles the marketplace of ideas. Combining Zen Buddhist practices with psychological concepts, Guan suggests fostering our "beginner's mind"—a way of engaging with the world without preconceptions—to seek mutual understanding in a polarized world."

    https://www.ted.com/talks/cecilia_guan_the_benefits_of_fostering_beginner_s_mind

    This podcast doesn't specificaly target English teachers, but the information is useful for everyone. It can help us be more open-minded when interacting with people who have different opinions, or make it easier for us to put ourselves in the position of a student, or person only learning something we already learned and understand.
