    Hi!
    this is a little buggette i think.

    if you cut an audio part you’ ll got clicks at the cut points even if you don’t move the obtained cutted parts.

    thanx

    If there is a click, then it’s just a single sample silence. The reason is that bar/beat time based arrangements are not using samples as internal resolution. So cutting at some bar-beat position is likely to be at a fractional sample position. If your arrangement is created with the Linear time resolution option, you won’t see this problem. I will check up on my code for converting bar/beat-time to sample-time. I should be able to obtain sample continuity if I am careful with how I round off fractional sample positions.

    I thought the problem is that there aren’t zero crossings at the cut point – which results in clicking when the audio plays back.

    I have been editing the audio in an external editor (adding very small fades at the start and end of the sample) to prevent clicks.

    I think I have request this before, but when we cut audio clips Podium should automatically create zero-crossings. I requested this at the same time I requested “per clip” fade in/outs (ALA Tracktion, anyone?)

    As I understood it, I think lalo had a single wave file which he then used the scalpel tool to split into two events without moving them. This can introduce a single sample offset for the second event, due to what I described above. Audio event fade in/out is on the plan.

    great!..thanx for the reply…so i’ll be able to see anyway bar/beats divisions with the linear time option?
    EDIT : nope it’s a ‘time’ visualization…for video soundtrack editing?

    Not just soundtrack editing, but any kind of recording where you don’t need bar/beats. An example is the mastering arrangement in the Freebees demo project.
