ADPCM V1.3.4 Available

[Mark DiVecchio]

Yet another version, V1.3.4, of ADPCM can be downloaded from my web page.

1. Added the sample rate into the automatically generated filename when "Dump Clip to Disk" menu item is selected.

2. Changed the "Dump Clip to Disk" menu item to have a submenu that lets you dump the entire clip as it originally did or to just dump the repeating segment. NOTE that dumping the repeating segment of a 4bit ADPCM clip may not be useful because the State
Machine Initialization has not been taken into account.

3. When you export to mp3 & 16 bit raw formats, the 16 bit little-endian PCM raw data is saved in a file named <sound file>_<clip number>_16bit_little_endian_PCM_<sample rate>.raw. This file can be easily imported into Audacity:

Select Import -- Raw Data
Pick the .raw file created by [Export mp3]
Select Encoding: Signed 16 bit PCM
Select Byte order: Little-endian
Select Channels: 1
Select Sample rate: 5512/11025/22050 as necessary
Press [Import]

4. I found that the "Exporting one clip to mp3" function was used more than "Export All Clips to mp3". The [Export mp3] button on the main window now does the first function. You can access the second function from the index popup menu.

5. If you hold down the shift key when you click on [Export mp3], ADPCM will use the long play method which will export the clip including the number of repeats in the "Rep" field.

6. Added the option to the Edit Clip window to replace a sound with silence. The program does not just delete the sound but replaces it with 0.01 seconds of silence. This was suggested by a member of the OGR Forum.

7. More minor bug fixes (these are the only kind of bugs remaining).


--- A reminder to always work with a copy of your sound file. ADPCM makes changes/edits
to the sound file immediately without confirmation. ---
