What is Simple Sounds?

Simple Sounds is a SMAPI Modding Resource which allows the import of Sound Files for use in Events or other Mods.
Namely, this allows Sounds to be imported via a Content Pack and then referenced in events when using /playSound {sound}



How do I use Simple Sounds? 
For Mod Authors, usage is similar to other SMAPI Content Packs:


1.) Create a manifest.json
Follow the SMAPI Manifest Format
You will need a ContentPackFor entry pointed to SimpleSounds:
"ContentPackFor": {
"UniqueID": "BleakCodex.SimpleSounds"
},


2.) Create a content.json
The format is as follows:

{
"Sounds" : [
{
  "Name": "{REQUIRED}",
  "FromFile": "{REQUIRED}",
  "Loop": {OPTIONAL - DEFAULT "false"},
  "InstanceLimit" : {OPTIONAL - Default "1"},
  "LimitBehavior" : {OPTIONAL - Default "FailToPlay" - {FailToPlay | ReplaceOldest} }
},
       ...
]
}

• Name
  

The Name of the sound that will be added to the SDV Soundbank. Can be referenced during events via /playSound {Name}

• FromFile
  

The directory and fileName of the sound you're adding. SDV supports .WAV files, so other formats will need to be converted.

• Loop
  

If the sound should be looped until stopped.

• InstanceLimit
  

How many instances of this sound can be playing at once, 0 = Unlimited

• LimitBehavior
  

Can either be {FailToPlay | ReplaceOldest} - if an instance limit is specified, once the limit is hit will determine if the oldest instance should stop, or if the newest instance should not play}


3.) Include your .WAV files and copy your Content Pack into the Stardew Valley/Mods folder


Done!
Once complete this sound will be accessible from the in-build SDV Soundbank, meaning you'll have access to it in events with:
/playSound {Name}
Or via other mods which leverage the Stardew Valley Soundbank.



Feature Requests
There are other mods which allow the replacement of sounds so I would recommend them over this one if that is your need.
It's likely possible to add music as well if there is a use-case and another mod hasn't already solved that.
Otherwise I will probably aim to keep this mod simple in order to keep maintainability low and compatibility high.
