I have a solution for this. In fact, I just got done figuring out what needed to be done but I decided it would be wise to search to see if anyone else talked about this.Originally Posted by fenderbender
BEFORE READING, note that I need a way to modify the volume on a batch of .wav files. The method I describe will work but will be time consuming without it.
EDIT: I have modified all the files. See post #12 in this thread.
]First things first. Make a backup of the sound files in case you screw something up.
Step 1: Browse to the iGuidance installation folder (ie., C:\Program Files\iNav\iGuidance\)
Step 2: Click File > New Folder and name it Snd_Backup
Step 3: Double click Snd folder
Step 4: Click Edit > Select All
Step 5: Click Edit > Copy
Step 6: Go back to the installation folder (see step 1)
Step 7: Right-click on the Snd_Backup folder and select Paste
Determine Volume Preference
This part takes a little bit to play with because everyone's hardware and set up is difference. It's not hard though so just bare with me.
Step 1: Start some music playing in CF (or any front-end) (Use your front-end because different programs will play at different volume levels.)
Step 2: Launch iGuidance
Step 3: Select Menu > Volume
Step 4: Press the Test button (Voice should be about equal to the music playing)
Step 5: Lower the iGuidance volume slide to about one-quarter (1/4 or 25%)
Step 6: Press the Test button (The overall sound should have gotten lower. Adjust the volume slide to get the lowering volume set to your preferred level)
Step 7: Now open the Dest.wav file in the Snd folder with Sound Recorder (C:\Windows\System32\sndrec32.exe)
Step 8: Click Effects > Increase Volume (by 25%) Do this two or three times but be sure to keep track of how many times you do this
Step 9: Click File > Save (leave the file open; do not close yet)
Step 10: Go back into iGuidance and click the Test button. (The voice should be slightly louder than the music.)
Step 11: Repeat steps 8-10 until the level is where you want it. (Don't forget to keep track of how many times you increased the volume.) It took about 8 increases to reach my preferance.
Now here's the bad part. There are 85 more files that still need the volume raised. At this point I only know how to manually do each one as described in steps 7-11. Granted, it's not hard work but would be time consuming. Right now I need a program that can take a batch of .wav files and increase the volume. I'll start doing some searching but maybe someone already knows of one. (Command-line based would be preferred.)
