+DEPRECATED APIS
+===============
+Version 0.9.0 deprecated the per-sample reading and seeking APIs and replaced them with versions that work on the resolution
+of a PCM frame instead. For example, given a stereo WAV file, previously you would pass 2 to drwav_read_f32() to read one
+PCM frame, whereas now you would pass in 1 to drwav_read_pcm_frames_f32(). The old APIs would return the number of samples
+read, whereas now it will return the number of PCM frames. Below is a list of APIs that have been deprecated and their
+replacements.
+
+    drwav_read()                     -> drwav_read_pcm_frames()
+    drwav_read_s16()                 -> drwav_read_pcm_frames_s16()
+    drwav_read_f32()                 -> drwav_read_pcm_frames_f32()
+    drwav_read_s32()                 -> drwav_read_pcm_frames_s32()
+    drwav_seek_to_sample()           -> drwav_seek_to_pcm_frame()
+    drwav_write()                    -> drwav_write_pcm_frames()
+    drwav_open_and_read_s16()        -> drwav_open_and_read_pcm_frames_s16()
+    drwav_open_and_read_f32()        -> drwav_open_and_read_pcm_frames_f32()
+    drwav_open_and_read_s32()        -> drwav_open_and_read_pcm_frames_s32()
+    drwav_open_file_and_read_s16()   -> drwav_open_file_and_read_pcm_frames_s16()
+    drwav_open_file_and_read_f32()   -> drwav_open_file_and_read_pcm_frames_f32()
+    drwav_open_file_and_read_s32()   -> drwav_open_file_and_read_pcm_frames_s32()
+    drwav_open_memory_and_read_s16() -> drwav_open_memory_and_read_pcm_frames_s16()
+    drwav_open_memory_and_read_f32() -> drwav_open_memory_and_read_pcm_frames_f32()
+    drwav_open_memory_and_read_s32() -> drwav_open_memory_and_read_pcm_frames_s32()
+    drwav::totalSampleCount          -> drwav::totalPCMFrameCount
+
+Rationale:
+    1) Most programs will want to read in multiples of the channel count which demands a per-frame reading API. Per-sample
+       reading just adds complexity and maintenance costs for no practical benefit.
+    2) This is consistent with my other decoders - dr_flac and dr_mp3.
+
+These APIs will be removed completely in version 0.10.0. You can continue to use drwav_read_raw() if you need per-sample
+reading.

+
+/*
+USAGE
+=====
+This is a single-file library. To use it, do something like the following in one .c file.
+    #define DR_WAV_IMPLEMENTATION
+    #include "dr_wav.h"
+
+You can then #include this file in other parts of the program as you would with any other header file. Do something
+like the following to read audio data:
+
+    drwav wav;
+    if (!drwav_init_file(&wav, "my_song.wav")) {
+        // Error opening WAV file.
+    }
+
+    drwav_int32* pDecodedInterleavedSamples = malloc(wav.totalPCMFrameCount * wav.channels * sizeof(drwav_int32));
+    size_t numberOfSamplesActuallyDecoded = drwav_read_pcm_frames_s32(&wav, wav.totalPCMFrameCount, pDecodedInterleavedSamples);
+
+    ...
+
+    drwav_uninit(&wav);
+
+You can also use drwav_open() to allocate and initialize the loader for you:
+
+    drwav* pWav = drwav_open_file("my_song.wav");
+    if (pWav == NULL) {
+        // Error opening WAV file.
+    }
+
+    ...
+
+    drwav_close(pWav);
+
+If you just want to quickly open and read the audio data in a single operation you can do something like this:
+
+    unsigned int channels;
+    unsigned int sampleRate;
+    drwav_uint64 totalPCMFrameCount;
+    float* pSampleData = drwav_open_file_and_read_pcm_frames_f32("my_song.wav", &channels, &sampleRate, &totalPCMFrameCount);
+    if (pSampleData == NULL) {
+        // Error opening and reading WAV file.
+    }
+
+    ...
+
+    drwav_free(pSampleData);
+
+The examples above use versions of the API that convert the audio data to a consistent format (32-bit signed PCM, in
+this case), but you can still output the audio data in its internal format (see notes below for supported formats):
+
+    size_t samplesRead = drwav_read_pcm_frames(&wav, wav.totalPCMFrameCount, pDecodedInterleavedSamples);
+
+You can also read the raw bytes of audio data, which could be useful if dr_wav does not have native support for
+a particular data format:
+
+    size_t bytesRead = drwav_read_raw(&wav, bytesToRead, pRawDataBuffer);
+
+
+dr_wav can also be used to output WAV files. This does not currently support compressed formats. To use this, look at
+drwav_open_write(), drwav_open_file_write(), etc. Use drwav_write_pcm_frames() to write samples, or drwav_write_raw()
+to write raw data in the "data" chunk.
+
+    drwav_data_format format;
+    format.container = drwav_container_riff;     // <-- drwav_container_riff = normal WAV files, drwav_container_w64 = Sony Wave64.
+    format.format = DR_WAVE_FORMAT_PCM;          // <-- Any of the DR_WAVE_FORMAT_* codes.
+    format.channels = 2;
+    format.sampleRate = 44100;
+    format.bitsPerSample = 16;
+    drwav* pWav = drwav_open_file_write("data/recording.wav", &format);
+
+    ...
+
+    drwav_uint64 samplesWritten = drwav_write_pcm_frames(pWav, frameCount, pSamples);
+
+
+dr_wav has seamless support the Sony Wave64 format. The decoder will automatically detect it and it should Just Work
+without any manual intervention.
+
+
+OPTIONS
+=======
+#define these options before including this file.
+
+#define DR_WAV_NO_CONVERSION_API
+  Disables conversion APIs such as drwav_read_pcm_frames_f32() and drwav_s16_to_f32().
+
+#define DR_WAV_NO_STDIO
+  Disables drwav_open_file(), drwav_open_file_write(), etc.
+
+
+
+QUICK NOTES
+===========
+- Samples are always interleaved.
+- The default read function does not do any data conversion. Use drwav_read_pcm_frames_f32(), drwav_read_pcm_frames_s32()
+  and drwav_read_pcm_frames_s16() to read and convert audio data to 32-bit floating point, signed 32-bit integer and
+  signed 16-bit integer samples respectively. Tested and supported internal formats include the following:
+  - Unsigned 8-bit PCM
+  - Signed 12-bit PCM
+  - Signed 16-bit PCM
+  - Signed 24-bit PCM
+  - Signed 32-bit PCM
+  - IEEE 32-bit floating point
+  - IEEE 64-bit floating point
+  - A-law and u-law
+  - Microsoft ADPCM
+  - IMA ADPCM (DVI, format code 0x11)
+- dr_wav will try to read the WAV file as best it can, even if it's not strictly conformant to the WAV format.

+                    to return as soon as the data chunk is found. Any chunks after the data chunk will be ignored.
+
+drwav_init() is equivalent to "drwav_init_ex(pWav, onRead, onSeek, NULL, pUserData, NULL, 0);".
+
+The onChunk callback is not called for the WAVE or FMT chunks. The contents of the FMT chunk can be read from pWav->fmt

+      drwav_open_file_and_read_f32()   -> drwav_open_file_and_read_pcm_frames_f32()
+      drwav_open_file_and_read_s32()   -> drwav_open_file_and_read_pcm_frames_s32()
+      drwav_open_memory_and_read_s16() -> drwav_open_memory_and_read_pcm_frames_s16()
+      drwav_open_memory_and_read_f32() -> drwav_open_memory_and_read_pcm_frames_f32()
+      drwav_open_memory_and_read_s32() -> drwav_open_memory_and_read_pcm_frames_s32()
+      drwav::totalSampleCount          -> drwav::totalPCMFrameCount
+  - API CHANGE: Rename drwav_open_and_read_file_*() to drwav_open_file_and_read_*().
+  - API CHANGE: Rename drwav_open_and_read_memory_*() to drwav_open_memory_and_read_*().
+  - Add built-in support for smpl chunks.
+  - Add support for firing a callback for each chunk in the file at initialization time.
+    - This is enabled through the drwav_init_ex(), etc. family of APIs.
+  - Handle invalid FMT chunks more robustly.
+
+v0.8.5 - 2018-09-11
+  - Const correctness.
+  - Fix a potential stack overflow.
+
+v0.8.4 - 2018-08-07
+  - Improve 64-bit detection.
+
+v0.8.3 - 2018-08-05
+  - Fix C++ build on older versions of GCC.
+
+v0.8.2 - 2018-08-02
+  - Fix some big-endian bugs.
+
+v0.8.1 - 2018-06-29
+  - Add support for sequential writing APIs.
+  - Disable seeking in write mode.
+  - Fix bugs with Wave64.
+  - Fix typos.
+
+v0.8 - 2018-04-27
+  - Bug fix.
+  - Start using major.minor.revision versioning.

+
+v0.7c - 2018-02-01
+  - Set drwav.bytesPerSample to 0 for all compressed formats.
+  - Fix a crash when reading 16-bit floating point WAV files. In this case dr_wav will output silence for
+    all format conversion reading APIs (*_s16, *_s32, *_f32 APIs).
+  - Fix some divide-by-zero errors.
+
+v0.7b - 2018-01-22
+  - Fix errors with seeking of compressed formats.
+  - Fix compilation error when DR_WAV_NO_CONVERSION_API
+
