Editing track clips is at the heart of any audio editor. It’s the weakest part of our alpha release so far. You can’t copy, paste, split, join, or drag multiple clips yet, and it’s really hard to accomplish tasks that all the other editors make simple.
However, it’s all on it’s way, but for now we wanted to point out what “is” there. There are some cool features in there now that all have to do with how you trim a track clip.
Trim: The simplest of course, but this allows you to modify the start/end point of your clip. Just mouse-over the right or left edge of a clip, and you’ll see a hilite. Click and drag to the left or right and the clip will be trimmed as you expect.
Loop: Audio clips that are dragged into the editor have metadata about them that indicate the clip’s tempo, beats, key, etc. If the metadata indicates that the clip is “Loopable”, then the trim process allows you to endlessly expand the clip. Currently in the alpha all the available clips are “Loopable”. You’ll see a vertical white line on the clip where the loop starts over. All the clip trim modes listed here support “Loopable” clips.
Push: This mode keeps one side of the clip constant, while modifying the other. To try this out, hold down the control-key on pc, command-key on mac, while trimming a clip. What you’ll notice is that that the end of the clip you are dragging remains as you had it while the other side is trimmed.
Slide: What this does, is to keep the track start/end positions locked, and allows you to drag the audio inside the clip. To try this out, hold down the control-key on pc, command-key on mac while dragging the center of a clip. It’s cool because let’s say you’ve spent some time trimming a vocal clip down, and you’ve got the position on the track just right, then you notice that you didn’t quite trim it properly. You can easily fix it by using the Slide feature.
Reverse: Pretty straight forward, or backwards rather. Right-click a track clip and choose “Reverse Clip”. It will do what you expect. Also note that the effects on a clip will be re-processed, so we are not just reversing the clip as is.
Stretch: This will lengthen or shorten a clip over time without affecting it’s pitch. As with most pitch-shifting algorithms, there is a limit to how far you can stretch before the quality really starts to degrade. But if you stretch a clip within 10-20% of it’s original value, it sounds pretty good. To try this out, hold down the control-key AND the shift-key at the same time and drag the end of a clip. For mac users, hold down the command-key AND the shift-key. The clip will be re-processed. Note that each clip maintains a reference to it’s original unprocessed audio, and performs the time-stretching on the original, so that we don’t stretch an already stretched clip!
