Using encoding.txt

encoding.txt is a file that controls sound compile parameters, like compression, loop points, sample rate, normalization, etc.

How to use​

Download lame_enc.dll from the LAME site and drop it into the game/bin/win64 folder of your game. Then create a encoding.txt file in the directory of your .WAV sound.

lamedll_location

warning

encoding.txt only works with sound files of the .WAV format.

Making looping sounds​

To make looping sounds, create a encoding.txt in a directory where your sounds are located.

sounds_wav

Then, you must have a files vector like this present in your file.

<!-- kv3 encoding:text:version{e21c7f3c-8a33-41c5-9977-a76d3a32aa0d} format:generic:version{7412167c-06e9-4698-aff2-e63eb59037e7} -->
{
        files =
	[
		{
				fileName = "soundname1.wav"
				loop =
				{	
					loop_start_time = 0
					loop_end_time =  11.428526
				}				
		},
	
		{
				fileName = "soundname3.wav"
				loop =
				{	
					loop_start_sample = 443016
					loop_end_sample =  3810374
                                        crossfade_ms = 1
				}
		},
	]
}

Near the filename of your sound, have a loop block with either loop_start_time/loop_end_time in seconds defined, or loop_start_sample/loop_end_sample in audio sample time.

Applying global compression​

To compress all .wav files in your addon enmasse to keep the compiled sound filesize low, you can create a encoding.txt with these parameters in content/sounds directory:

<!-- kv3 encoding:text:version{e21c7f3c-8a33-41c5-9977-a76d3a32aa0d} format:generic:version{7412167c-06e9-4698-aff2-e63eb59037e7} -->
{
	compress = 
	{
		format = "mp3"
		minbitrate = 128
		maxbitrate = 320
		vbr = 1
	}
}

To override the compression settings per-directory, a new encoding.txt with different parameters can be created in a directory closest to your sounds.

encoding_hierarchy

To change the compression settings on per-file basis, a files vector like this must be present in your encoding.txt file.

perfile

encoding.txt file​

<!-- kv3 encoding:text:version{e21c7f3c-8a33-41c5-9977-a76d3a32aa0d} format:generic:version{7412167c-06e9-4698-aff2-e63eb59037e7} -->
{
	compress = 
	{
		format = "mp3"
		minbitrate = 128
		maxbitrate = 320
		vbr = 1
	}
        files =
	[
		{
				fileName = "soundname1.wav"
				loop =
				{	
					loop_start_time = 0
					loop_end_time =  11.428526
				}
				resample =
				{
					rate = 44100
				}
		},

		{
				fileName = "soundname2.wav"
				loop =
				{	
					loop_start_time = 0
					loop_end_time =  32
				}
                                compress = 
                                {
                                        format = "PCM" // Set format to PCM to disable compression.
                                }
		},

		{
				fileName = "soundname3.wav"
				loop =
				{	
					loop_start_sample = 443016
					loop_end_sample =  3810374
                                        crossfade_ms = 1
				}
		},
	]
}
