Item

Description

Time signature

Displays the number of beats in your clip and the note that receives one beat.

You can double-click the value to edit it

ACID type

Displays the clip’s ACID type.

Click the down arrow Sound Forge Pro b downarrow2 ACID Properties and choose a setting from the drop-down list to change the clip type:

One-Shot

Choose One-Shot if you want ACID to treat your file as a one-shot.

One-shots are RAM-based audio clips that do not change tempo or pitch with an ACID project and are not designed to loop. Sounds such as cymbal crashes and sound bites could be considered one-shots. Longer files can be treated as one-shots if your computer has sufficient memory.

Loop

Choose Loop and specify a Number of beats and Root note for transposing if you want ACID to treat your file as a loop.

Loops are small audio clips that are designed to create a repeating beat or pattern. Loops are usually one to four measures long and are stored completely in RAM for playback. Loop files change tempo and can pitch shift with an ACID project.

  • Root note for transposing: Click the down arrow Sound Forge Pro b downarrow2 ACID Properties and choose a note from the drop-down list to set the base note for tracks that you want to conform to the project key.

    If you do not want a track transposed to the project key (a track that contains a drum sample, for example) choose Don’t transpose.

  • Number of beats: Double-click to edit the length of th
    e file. Selecting a value that does not match the actual file will cause ACID to play the loop at a different speed than normal. For example, specifying a length of 8 beats for a 4-beat loop will cause the loop to play at half speed at any given tempo.

ACID Beatmapped

Choose ACID Beatmapped if you want to add key and tempo information to a long audio file. By default, ACID will start the Beatmapper Wizard for files longer than 30 seconds.

  • Root note for transposing: Click the down arrow Sound Forge Pro b downarrow2 ACID Properties and choose a note from the drop-down list to set the base note for tracks that you want to conform to the project key.

    If you do not want a track transposed to the project key (a track that contains a drum sample, for example) choose Don’t transpose.

  • Tempo: Double-click to edit the original tempo of the clip.  

  • Downbeat offset (samples): Double-click to edit the location (in samples) of the track’s first downbeat.
