FREE OPEN SOURCE AUDIO RECORDING AND EDITING SOFTWARE
USING AUDACITY
WHERE TO FIND IT
• Audacity• http://audacity.sourceforge.net/• Or Google “Audacity audio”
• Audacity manual• http://audacity.sourceforge.net/manual-1.2/
• Audacity tutorials• http://audacity.sourceforge.net/manual-1.2/tutorials.html
• LAME encoder (for exporting.mp3s)• http://lame.buanzo.com.ar/• Audacity provides a link the first time you attempt to
make an ,mp3
AUDIO FORMATS
• Lots of formats• .wav – very common, uncompressed (big files), lossless,
nearly universal playback ability• .mp3 – very common, compressed (little files), lossy,
nearly universal playback ability • .wma – Windows audio, may have Digital Rights
Management for copy protection• m4p – ITunes format – WILL have Digital Rights
Management for copy protection (probably won’t play back on another computer)
• .ogg – free, open source, uses Vorbis format to play• Librivox – public domain audio books
• .ra – Real Audio, use in decline
CHOOSING YOUR MICROPHONE AND SPEAKERS
• Edit>Preferences>Devices• Set your mike, speakers, stereo or mono• I need to choose a different mike than the
Connect mike• Use a moderately priced headset for best results
RECORDING AND PLAYBACK
• Just like a tape recorder or VCR• Pause, play, stop, rewind, fast forward, record
• Recording shows up as a waveform• Useful to find silence, pauses or extraneous noises if
editing
EFFECTS MENU
• Effects>Amplify• May have to enable “clipping”
to apply the effect
• Effects>Fade In• Effects>Fade Out
• Effects>Remove Noise
EDITING TRACKS
• Playback to find the spot you want to cut• Use the waveform to find
the silences
• Use the selection tool to select the cut• Left click and drag• Hit Delete or Cut to make
the edit• Ctrl + Z to undo an edit
• You can also replace the selection with silence
cut Replace withsilence
Selection tool
EXPORTING (SAVING) FILES
• You don’t save sound files, you Export them
• File>Export>Choose folder, filename, and format
• MP3s require a download of a LAME encoder• Audacity guides you though
the process
• Because .wav is lossless, I edit and combine in .wav, and convert to .mp3 when I’m done
IMPORTING AND COMBINING TRACKS
• Record and export all your clips• Import all your clips• Don’t click Open, as they will open up in different windows• Import opens them all up in same window
• Copy and paste second clip onto end of first track• Close clip • Copy and paste third clip onto end of first track• Close clip• Repeat until al the clips are on one track
• Save the whole thing with a new filename when you’re done
LAME ENCODER
• Export as MP3• You’ll get this prompt the first
time• Click Download• Follow the links (there are 2)
• Download LAME• Click the .exe file• Export the file!
MIXING TRACKS
• Import tracks you want to mix• If music, make sure you have rights• LOTS of public domain music out there• http://www.mfiles.co.uk/ is where I got the Bach
• Edit tracks to same running time• Use Effects menu(Amplify, Fade In, Fade Out) as
needed• Export• Will automatically mix tracks together
