How to use 12sonic audio player -- the basics

1. Open a song by clicking the Open button. You can select any supported audio file that you have on your computer's local drive(s). (.mp3, .m4a, .wav)

2. Control the song playback by clicking the Play or Pause buttons. Or, use the spacebar to toggle Play/Pause.

3. Navigate the song by dragging the position indicator or using the forward and back arrows on your keyboard to jump ahead or back.

4. When the position indicator reaches the end of a song segment (for example: the end of the intro), click the New button (or press the down arrow key) to create a segment at this position.

5. Once you have created a new segment, a button will be created to mark the position in the song. Clicking this button starts the audio at the beginning of the segment. Regardless of how many segments you define, there will always be a segment at the end of the song called "{end}" -- this segment can be clicked just like any other segment.

Creating a segment

To add a segment, wait for the position indicator to reach the end of the first song segment (for example: the intro) then click New or push the down arrow on the keyboard.

Looping a segment

To play a segment over and over, click the "L" button on the segment itself. The looped segment will turn red and all other segments will turn gray. When in loop mode, the looped segment will play over and over automatically. To turn off loop mode, click the yellow "L" on the looped segment.

Renaming a segment

To rename a segment, click the "R" button on the segment itself. A dialog will appear allowing you to give the segment any name you'd like. Typically this is something like "intro" or "verse 1" etc.

Deleting a segment

To delete a segment, click the "X" button on the segment itself. The segment will be removed from the song structure entirely. Also, you can click "Clear" to clear all segments at once for the song.

Saving a song structure

Once you have defined the structure of a song, click "Save" to make the same song structure load the next time the same audio file is opened. This way you can define the structure of all the songs you are currently learning and re-open each song one at a time and the song structure will be automatically loaded based on what you defined previously. Each time you click "Save" the existing saved structure for the current song will be overwritten. Structures are linked to songs based on the filename of the audio file. So, two separate song structures must reference audio files on disk that have two unique filenames.

Control playback speed (NEW in version 1.1)

Once a song is loaded, use the Fast and Slow buttons to increase or decrease the playback speed of the song. Valid playback speed ranges from 0.5 (half the original speed) to 2.0 (twice the original speed). Keyboard shortcuts: use the period key (.) to increase playback speed and comma (,) to decrease playback speed. To reset the playback speed to normal (1.0), click the number showing the current playback speed.

Intelligent segment coloring

12sonic audio player will automatically color the segments in the song based on the names you give them. Two segments will have the same color if they have the same name, or if they have the same text to the left of the first space in the name. (ex. "chorus" and "chorus" will have the same color, "chorus 1" and "chorus 2" will have the same color, "a test name" and "a second test name" will have the same color)

How come the timing on one of my MP3s seems off based on where I set the segments?

Occasionally, there may be an MP3 that 12sonic audio player can't accurately determine the current playback position from. In this case, the segments start or end time can be a little off. Often times this isn't noticeable, but if you are experiencing this issue you can use a program like iTunes to convert the MP3 to another format like WAV and the issue will go away. Sometimes this issue can be caused by embedded album artwork in an MP3. If you need to use MP3s, try removing any embedded album artwork using a program like iTunes. Then, play the song in 12sonic audio player and re-define your segments.

I'm seeing 'App not authorized' but I did purchase the full version. How can I fix this?

Start by making sure you are connected to the internet so 12sonic audio player can verify your license from the Chrome Web Store™. Then, verify you are signed into Google Chrome™ as the user that purchased the full version. Then, run 12sonic audio player and when the App not authorized dialog comes up, click "Re-check license." This should resolve the issue.
