+# Playing audio with speakers
+CC: Tweaked's speaker peripheral provides a powerful way to play any audio you like with the @{speaker.playAudio}
+method. However, for people unfamiliar with digital audio, it's not the most intuitive thing to use. This guide provides
+an introduction to digital audio, demonstrates how to play music with CC: Tweaked's speakers, and then briefly discusses
+the more complex topic of audio processing.
+
+## A short introduction to digital audio
+When sound is recorded it is captured as an analogue signal, effectively the electrical version of a sound
+wave. However, this signal is continuous, and so can't be used directly by a computer. Instead, we measure (or *sample*)
+the amplitude of the wave many times a second and then *quantise* that amplitude, rounding it to the nearest
+representable value.
+
+This representation of sound - a long, uniformally sampled list of amplitudes is referred to as [Pulse-code
+Modulation][PCM] (PCM). PCM can be thought of as the "standard" audio format, as it's incredibly easy to work with. For
+instance, to mix two pieces of audio together, you can just samples from the two tracks together and take the average.
+
+CC: Tweaked's speakers also work with PCM audio. It plays back 48,000 samples a second, where each sample is an integer
+between -128 and 127. This is more commonly referred to as 48kHz and an 8-bit resolution.
+
+Let's now look at a quick example. We're going to generate a [Sine Wave] at 220Hz, which sounds like a low monotonous
+hum. First we wrap our speaker peripheral, and then we fill a table (also referred to as a *buffer*) with 128×1024
+samples - this is the maximum number of samples a speaker can accept in one go.
+
+In order to fill this buffer, we need to do a little maths. We want to play 220 sine waves each second, where each sine
+wave completes a full oscillation in 2π "units". This means one seconds worth of audio is 2×π×220 "units" long. We then
+need to split this into 48k samples, basically meaning for each sample we move 2×π×220/48k "along" the sine curve.
+
+```lua {data-peripheral=speaker}
+local speaker = peripheral.find("speaker")
+
+local buffer = {}
+local t, dt = 0, 2 * math.pi * 220 / 48000
+for i = 1, 128 * 1024 do
+    buffer[i] = math.floor(math.sin(t) * 127)
+    t = (t + dt) % (math.pi * 2)
+end
+
+speaker.playAudio(buffer)
+```
+
+## Streaming audio
+You might notice that the above snippet only generates a short bit of audio - 2.7s seconds to be precise. While we could
+try increasing the number of loop iterations, we'll get an error when we try to play it through the speaker: the sound
+buffer is too large for it to handle.
+
+Our 2.7 seconds of audio is stored in a table with over 130 _thousand_ elements. If we wanted to play a full minute of
+sine waves (and why wouldn't you?), you'd need a table with almost 3 _million_. Suddenly you find these numbers adding
+up very quickly, and these tables take up more and more memory.
+
+Instead of building our entire song (well, sine wave) in one go, we can produce it in small batches, each of which get
+passed off to @{speaker.playAudio} when the time is right. This allows us to build a _stream_ of audio, where we read
+chunks of audio one at a time (either from a file or a tone generator like above), do some optional processing to each
+one, and then play them.
+
+Let's adapt our example from above to do that instead.
+
+```lua {data-peripheral=speaker}
+local speaker = peripheral.find("speaker")
+
+local t, dt = 0, 2 * math.pi * 220 / 48000
+while true do
+    local buffer = {}
+    for i = 1, 16 * 1024 * 8 do
+        buffer[i] = math.floor(math.sin(t) * 127)
+        t = (t + dt) % (math.pi * 2)
+    end
+
+    while not speaker.playAudio(buffer) do
+        os.pullEvent("speaker_audio_empty")
+    end
+end
+```
+
+It looks pretty similar to before, aside from we've wrapped the generation and playing code in a while loop, and added a
+rather odd loop with @{speaker.playAudio} and @{os.pullEvent}.
+
+Let's talk about this loop, why do we need to keep calling @{speaker.playAudio}? Remember that what we're trying to do
+here is avoid keeping too much audio in memory at once. However, if we're generating audio quicker than the speakers can
+play it, we're not helping at all - all this audio is still hanging around waiting to be played!
+
+In order to avoid this, the speaker rejects any new chunks of audio if its backlog is too large. When this happens,
+@{speaker.playAudio} returns false. Once enough audio has played, and the backlog has been reduced, a
+@{speaker_audio_empty} event is queued, and we can try to play our chunk once more.
+
+## Storing audio
+PCM is a fantastic way of representing audio when we want to manipulate it, but it's not very efficient when we want to
+store it to disk. Compare the size of a WAV file (which uses PCM) to an equivalent MP3, it's often 5 times the size.
+Instead, we store audio in special formats (or *codecs*) and then convert them to PCM when we need to do processing on
+them.
+
+Modern audio codecs use some incredibly impressive techniques to compress the audio as much as possible while preserving
+sound quality. However, due to CC: Tweaked's limited processing power, it's not really possible to use these from your
+computer. Instead, we need something much simpler.
+
+DFPWM (Dynamic Filter Pulse Width Modulation) is the de facto standard audio format of the ComputerCraft (and
+OpenComputers) world. Originally popularised by the addon mod [Computronics], CC:T now has built-in support for it with
+the @{cc.audio.dfpwm} module. This allows you to read DFPWM files from disk, decode them to PCM, and then play them
+using the speaker.
+
+Let's dive in with an example, and we'll explain things afterwards:
+
+```lua {data-peripheral=speaker}
+local dfpwm = require("cc.audio.dfpwm")
+local speaker = peripheral.find("speaker")
+
+local decoder = dfpwm.make_decoder()
+for chunk in io.lines("data/example.dfpwm", 16 * 1024) do
+    local buffer = decoder(chunk)
+
+    while not speaker.playAudio(buffer) do
+        os.pullEvent("speaker_audio_empty")
+    end
+end
+```
+
+Once again, we see the @{speaker.playAudio}/@{speaker_audio_empty} loop. However, the rest of the program is a little
+different.
+
+First, we require the dfpwm module and call @{cc.audio.dfpwm.make_decoder} to construct a new decoder. This decoder
+accepts blocks of DFPWM data and converts it to a list of 8-bit amplitudes, which we can then play with our speaker.
+
+As mentioned to above, @{speaker.playAudio} accepts at most 128×1024 samples in one go. DFPMW uses a single bit for each
+sample, which means we want to process our audio in chunks of 16×1024 bytes (16KiB). In order to do this, we use
+@{io.lines}, which provides a nice way to loop over chunks of a file. You can of course just use @{fs.open} and
+@{fs.BinaryReadHandle.read} if you prefer.
+
+## Processing audio
+As mentioned near the beginning of this guide, PCM audio is pretty easy to work with as it's just a list of amplitudes.
+You can mix together samples from different streams by adding their amplitudes, change the rate of playback by removing
+samples, etc...
+
+Let's put together a small demonstration here. We're going to add a small delay effect to the song above, so that you
+hear a faint echo about a second later.
+
+In order to do this, we'll follow a format similar to the previous example, decoding the audio and then playing it.
+However, we'll also add some new logic between those two steps, which loops over every sample in our chunk of audio, and
+adds the sample from one second ago to it.
+
+For this, we'll need to keep track of the last 48k samples - exactly one seconds worth of audio. We can do this using a
+[Ring Buffer], which helps makes things a little more efficient.
+
+```lua {data-peripheral=speaker}
+local dfpwm = require("cc.audio.dfpwm")
+local speaker = peripheral.find("speaker")
+
+-- Speakers play at 48kHz, so one second is 48k samples. We first fill our buffer
+-- with 0s, as there's nothing to echo at the start of the track!
+local samples_i, samples_n = 1, 48000
+local samples = {}
+for i = 1, samples_n do samples[i] = 0 end
+
+local decoder = dfpwm.make_decoder()
+for chunk in io.lines("data/example.dfpwm", 16 * 1024) do
+    local buffer = decoder(chunk)
+
+    for i = 1, #buffer do
+        local original_value = buffer[i]
+
+        -- Replace this sample with its current amplitude plus the amplitude from one second ago.
+        -- We scale both to ensure the resulting value is still between -128 and 127.
+        buffer[i] = original_value * 0.6 + samples[samples_i] * 0.4
+
+        -- Now store the current sample, and move the "head" of our ring buffer forward one place.
+        samples[samples_i] = original_value
+        samples_i = samples_i + 1
+        if samples_i > samples_n then samples_i = 1 end
+    end
+
+    while not speaker.playAudio(buffer) do
+        os.pullEvent("speaker_audio_empty")
+    end
+end
+```
+
+:::note Confused?
+Don't worry if you don't understand this example. It's quite advanced, and does use some ideas that this guide doesn't
+cover. That said, don't be afraid to ask on [Discord] or [IRC] either!
+:::
+
+It's worth noting that the examples of audio processing we've mentioned here are about manipulating the _amplitude_ of
+the wave. If you wanted to modify the _frequency_ (for instance, shifting the pitch), things get rather more complex.
+For this, you'd need to use the [Fast Fourier transform][FFT] to convert the stream of amplitudes to frequencies,
+process those, and then convert them back to amplitudes.
+
+This is, I'm afraid, left as an exercise to the reader.

+
+# Reusing code with require
+A library is a collection of useful functions and other definitions which is stored separately to your main program. You
+might want to create a library because you have some functions which are used in multiple programs, or just to split
+your program into multiple more modular files.
+
+Let's say we want to create a small library to make working with the @{term|terminal} a little easier. We'll provide two
+functions: `reset`, which clears the terminal and sets the cursor to (1, 1), and `write_center`, which prints some text
+in the middle of the screen.
+
+Start off by creating a file called `more_term.lua`:
+
+```lua {data-snippet=more_term}
+local function reset()
+  term.clear()
+  term.setCursorPos(1, 1)
+end
+
+local function write_center(text)
+  local x, y = term.getCursorPos()
+  local width, height = term.getSize()
+  term.setCursorPos(math.floor((width - #text) / 2) + 1, y)
+  term.write(text)
+end
+
+return { reset = reset, write_center = write_center }
+```
+
+Now, what's going on here? We define our two functions as one might expect, and then at the bottom return a table with
+the two functions. When we require this library, this table is what is returned. With that, we can then call the
+original functions. Now create a new file, with the following:
+
+```lua {data-mount=more_term:more_term.lua}
+local more_term = require("more_term")
+more_term.reset()
+more_term.write_center("Hello, world!")
+```
+
+When run, this'll clear the screen and print some text in the middle of the first line.
+
+## require in depth
+While the previous section is a good introduction to how @{require} operates, there are a couple of remaining points
+which are worth mentioning for more advanced usage.
+
+### Libraries can return anything
+In our above example, we return a table containing the functions we want to expose. However, it's worth pointing out
+that you can return ''anything'' from your library - a table, a function or even just a string! @{require} treats them
+all the same, and just returns whatever your library provides.
+
+### Module resolution and the package path
+In the above examples, we defined our library in a file, and @{require} read from it. While this is what you'll do most
+of the time, it is possible to make @{require} look elsewhere for your library, such as downloading from a website or
+loading from an in-memory library store.
+
+As a result, the *module name* you pass to @{require} doesn't correspond to a file path. One common mistake is to load
+code from a sub-directory using `require("folder/library")` or even `require("folder/library.lua")`, neither of which
+will do quite what you expect.
+
+When loading libraries (also referred to as *modules*) from files, @{require} searches along the *@{package.path|module
+path}*. By default, this looks something like:
+
+* `?.lua`
+* `?/init.lua`
+* `/rom/modules/main/?.lua`
+* etc...
+
+When you call `require("my_library")`, @{require} replaces the `?` in each element of the path with your module name, and
+checks if the file exists. In this case, we'd look for `my_library.lua`, `my_library/init.lua`,
+`/rom/modules/main/my_library.lua` and so on. Note that this works *relative to the current program*, so if your
+program is actually called `folder/program`, then we'll look for `folder/my_library.lua`, etc...
+
+One other caveat is loading libraries from sub-directories. For instance, say we have a file
+`my/fancy/library.lua`. This can be loaded by using `require("my.fancy.library")` - the '.'s are replaced with '/'
+before we start looking for the library.
+
+## External links
+There are several external resources which go into require in a little more detail:
+
+ - The [Lua Module tutorial](http://lua-users.org/wiki/ModulesTutorial) on the Lua wiki.
+ - [Lua's manual section on @{require}](https://www.lua.org/manual/5.1/manual.html#pdf-require).

 /**
- * The FS API allows you to manipulate files and the filesystem.
+ * The FS API provides access to the computer's files and filesystem, allowing you to manipulate files, directories and
+ * paths. This includes:
+ *
+ * <ul>
+ * <li>**Reading and writing files:** Call {@link #open} to obtain a file "handle", which can be used to read from or
+ * write to a file.</li>
+ * <li>**Path manipulation:** {@link #combine}, {@link #getName} and {@link #getDir} allow you to manipulate file
+ * paths, joining them together or extracting components.</li>
+ * <li>**Querying paths:** For instance, checking if a file exists, or whether it's a directory. See {@link #getSize},
+ * {@link #exists}, {@link #isDir}, {@link #isReadOnly} and {@link #attributes}.</li>
+ * <li>**File and directory manipulation:** For instance, moving or copying files. See {@link #makeDir}, {@link #move},
+ * {@link #copy} and {@link #delete}.</li>
+ * </ul>
+ *
+ * :::note
+ * All functions in the API work on absolute paths, and do not take the @{shell.dir|current directory} into account.
+ * You can use @{shell.resolve} to convert a relative path into an absolute one.
+ * :::
+ *
+ * ## Mounts
+ * While a computer can only have one hard drive and filesystem, other filesystems may be "mounted" inside it. For
+ * instance, the {@link dan200.computercraft.shared.peripheral.diskdrive.DiskDrivePeripheral drive peripheral} mounts
+ * its disk's contents at {@code "disk/"}, {@code "disk1/"}, etc...
+ *
+ * You can see which mount a path belongs to with the {@link #getDrive} function. This returns {@code "hdd"} for the
+ * computer's main filesystem ({@code "/"}), {@code "rom"} for the rom ({@code "rom/"}).
+ *
+ * Most filesystems have a limited capacity, operations which would cause that capacity to be reached (such as writing
+ * an incredibly large file) will fail. You can see a mount's capacity with {@link #getCapacity} and the remaining
+ * space with {@link #getFreeSpace}.
