How do I save in MP3 format?
The app does not ship with an MP3 encoder, due to licensing issues. You will need to download and install the kJams LAME.framework on our Downloads page, which is 32-bit only as of December 15, 2010. Unless you have a 64-bit version of LAME.framework, you'll need to run Sound Studio in 32-bit mode. Use the Finder's Get Info on the app icon on the disk, select "Open in 32-bit mode", and relaunch the app. The MP3 option should appear when you save.
How can I purge the temp files?
The only way to purge temp files is to save and close the file, and then reopen it. The temp files contain all your changes to the files since you last opened it, and are all required to construct the file that is saved, so the only way to purge them is to write everything to a single file and then to use that file.
How do I open a CD audio track?
To open a track on an audio CD, select File > Open, navigate to your Audio CD, and open your CD track directly. This file can then be edited and saved to the hard disk drive. All CD audio tracks will open up as 44.1kHz, 16-bit, stereo files.
How do I change the default sample rate?
In version 4.0.2 and later you can set the default sample rate to 48,000 Hz (or any other value) by
entering this in Terminal:
defaults write com.felttip.SoundStudio file.sampleRate 48000
How do I set the sample size to 24 bit?
The app handles all audio data as 32-bit float internally, so you do not need to set the sample size, except when saving. When saving to several file formats, you would set the sample size in the options for that file format in the save panel. You can also set the sample size from the Audio menu, but it's just the value that's used when saving and it doesn't affect the audio data within the app.
How do I avoid CD sector boundary errors?
The only solution I've found, and I haven't tested it, is to set the zoom to 588, or an integer multiple of 588, so that when you make a selection or move the insertion point, it always falls on a CD sector boundary. And when you make an edit, it should always fall on one of those boundaries.
How do I avoid pops due to plosives and esses (sibilants) in voice recordings?
While you could use a pop filter over your microphone, or apply digital filters to edit out the pops and esses, I've found the simple technique of speaking off-axis with respect to the microphone works much better. You do this by pointing the microphone at your mouth, but you face slightly to one side of the mic so that you're not breathing or talking into the mic. You should use a directional microphone to get the best results.
How far should I place the microphone for my voice recordings?
The closer you place the microphone, the more intimate and quiet your voice will sound. The farther away, the louder you can speak while still sounding natural. Also, moving the mic closer will emphasize the bass in your voice. While you could use the EQ in post-production to get more bass, you'll also increase the bass noise that way.
How can I get better sounding vocals with a different microphone?
I suggest using a good cardioid directional microphone, with the expensive condenser mics being the best choice, though a good dynamic mic with a clean mic amp would work as well. Dynamic mics tend to have more noise, but some people prefer their sound. A good digital recorder with a built-in mic also works great. The only issue with these higher quality microphones is that you might want to simulate the sound of a dynamic, which you can do using EQ to do a roll-off filter which removes the very high and very low frequencies.
How can I resize the selection?
Hold down the shift key and click and drag near the edge of the selection you want to modify. You can also use the keyboard arrow keys with the shift key to modify the selection. The first keystroke determines which edge of the selection gets changed, and subsequent keystrokes move the selection edge left and right. This is similar to how most text editing apps on the Mac work.
How do I fit a selection within a specific timeframe?
To change the duration of an entire audio file, select Filter > Pitch and Tempo and enter the desired total duration of the file. The duration is in the format “hours′′minutes′seconds.fraction” so 3′05.00 is three minutes and five seconds. (The symbol represents the prime mark for minutes and double prime mark for hours, but is entered with the apostrophe and double quote keys.) The pitch of the audio will stay the same.
How do I cross-fade two files?
Open two files and make sure they both have the same sample rate, sample size, and number of channels, but it’s not necessary. This example uses a cross-fade of five seconds, but you can use a different duration. Apply the Fade Out filter to the last five seconds of the first file. Apply the Fade In filter on the first five seconds of the second file. Select all of the second file and select Edit > Copy to put it on the clipboard. In the first file, click once at a point five seconds before its end, and use Edit > Mix Paste to mix the clipboard audio with the first file. The audio on the clipboard will be mixed on top of the first file starting from the insertion point, and the file will be extended to hold the new mix. By repeating this cross-fade on several songs, you can create a mix with seamless transitions between songs.
