'''BFWAV''' ('''B'''inary ca'''F'''e '''WAV'''e) is common file format for storing sound on [[Wii U]] and [[Nintendo Switch]]. The format is structured similarly to [https://en.wikipedia.org/wiki/WAV WAV], where there is one info section ("''fmt ''" in WAV, "''INFO''" in BFWAV) and one data section ("''data''" in WAV, "''DATA''" in BFWAV). The file consists of a header and two sections, [[#INFO|INFO]] and [[#DATA|DATA]]. All offsets in the file may be 0xFFFFFFFF if it links to nothing.

= File Format =
== Header ==
The file starts with a header as follows:

{|class="wikitable"
|-
! Offset !! Type !! Description
|-
| 0x00 || Char[4] || '''File magic'''. Always ''FWAV'' in ASCII.
|-
| 0x04 || UInt16 || {{BOM}}
|-
| 0x06 || UInt16 || '''Header size'''. Always 0x40 due to alignment.
|-
| 0x08 || UInt32 || '''[[#Version List|Version number]]'''.
|-
| 0x0C || UInt32 || '''File size''' in bytes.
|-
| 0x10 || UInt16 || '''Number of sections'''. Always 2.
|-
| 0x12 || UInt16 || '''Padding'''.
|-
| 0x14 || UInt16 || '''[[#INFO|INFO]] section flag'''. Always 0x7000.
|-
| 0x16 || UInt16 || '''Padding'''.
|-
| 0x18 || UInt32 || '''[[#INFO|INFO]] offset'''.
|-
| 0x1C || UInt32 || '''[[#INFO|INFO]] size''' in bytes.
|-
| 0x20 || UInt16 || '''[[#DATA|DATA]] section flag'''. Always 0x7001.
|-
| 0x22 || UInt16 || '''Padding'''.
|-
| 0x24 || UInt32 || '''[[#DATA|DATA]] offset'''.
|-
| 0x28 || UInt32 || '''[[#DATA|DATA]] size''' in bytes.
|-
| 0x2C || Byte[0x14] || '''Padding''' to align the data.
|-
| 0x40 || colspan=2 {{Unknown|End of header}}
|}

== INFO ==
The ''INFO'' section contains general information about the sound.

{|class="wikitable"
|-
! Offset !! Type !! Description
|-
| 0x00 || Char[4] || '''Section magic'''. Always ''INFO'' in ASCII.
|-
| 0x04 || UInt32 || '''Section size''' in bytes.
|-
| 0x08 || Byte || '''Sound encoding'''. 0 = PCM8, 1 = PCM16, 2 = DSP ADPCM, 3 = IMA ADPCM.
|-
| 0x09 || Byte || '''Loop'''. 0 = no loop, 1 = loop.
|-
| 0x0A || Byte[2] || '''Padding'''.
|-
| 0x0C || UInt32 || Sample rate.
|-
| 0x10 || UInt32 || '''Loop start in frames'''. 0 if not looping.
|-
| 0x14 || UInt32 || '''Loop end in frames'''. 0 if not looping.
|- bgcolor="#AAFFAA"
| colspan="3" align="center" | '''If [[#Header|version]] ≥ 0.1.2.0'''
|- bgcolor="#DDFFDD"
| 0x18 || UInt32 || '''Original loop start'''. 0 if not looping.
|- bgcolor="#FFAAAA"
| colspan="3" align="center" | '''Else'''
|- bgcolor="#DDFFDD"
| 0x18 || UInt32 || '''Reserved.'''
|}

Then follows a [[#Reference Table|reference table]] which points to the [[#Channel Info|channel infos]]. The section flag is 0x7100.

=== Channel Info ===
The ''Channel Info'' section contains an offset to the data and may contain ADPCM information. Each entry has the following structure:

{|class="wikitable"
|-
! Offset !! Type !! Description
|-
| 0x00 || UInt16 || '''Sound data offset flag'''. Always 0x1F00.
|-
| 0x02 || UInt16 || '''Padding'''.
|-
| 0x04 || Int32 || '''Sound data offset''', relative to 0x08 into the [[#DATA|DATA]] section.
|-
| 0x08 || UInt16 || '''[[#ADPCM Info|ADPCM info]] flag'''. Always 0x0300.
|-
| 0x0A || UInt16 || '''Padding'''.
|-
| 0x0C || Int32 || '''[[#ADPCM Info|ADPCM info]] offset''', relative to the start of this structure.
|-
| 0x10 || UInt32 || '''Reserved'''.
|}

==== ADPCM Info ====
{|class="wikitable"
|-
! Offset !! Type !! Description
|-
| 0x00 || UInt16[8][2] || 16-bit Coefficients.
|-
| 0x20 || UInt16 || Pred scale.
|-
| 0x22 || UInt16 || Yn 1.
|-
| 0x24 || UInt16 || Yn 2.
|-
| 0x26 || UInt16 || Loop Pred Scale.
|-
| 0x28 || UInt16 || Loop Yn 1.
|-
| 0x2A || UInt16 || Loop Yn 2.
|-
| 0x2C || UInt16 || '''Padding'''.
|}

== DATA ==
The ''DATA'' section contains all the sound data.

{|class="wikitable"
|-
! Offset !! Type !! Description
|-
| 0x00 || Char[4] || '''Section magic'''. Always ''DATA'' in ASCII.
|-
| 0x04 || UInt32 || '''S''' = '''Section size''' in bytes.
|-
| 0x08 || Byte['''S''' - 8] || '''Sound data'''.
|}

== Reference Table ==
A reference table is used to reference multiple structures. It has the following structure:

{|class="wikitable"
|-
! Offset !! Type !! Description
|-
| 0x00 || UInt32 || Number of references.
|}

The following structure follows. The amount is specified above.

{|class="wikitable"
|-
! Offset !! Type !! Description
|-
| 0x00 || UInt16 || '''Section flag''', to identify what structure it links to.
|-
| 0x02 || UInt16 || '''Padding'''.
|-
| 0x04 || Int32 || '''Offset to a structure''', relative to the start of the header structure.
|}
