Audio Engineer Looking to Change Careers
Audio DSP is definitely the deep end of the pool. I believe the Zig programming language owes its creation to Andrew Kelley (the creator) trying to write stuff for an audio workbench going "damn, this is really hard to do with C, why does C suck so much" and just creating a language that's like C but without the bad parts to do it himself. I'm not joking, this is literally the origin of Zig as I've heard it from a podcast, and here is Andrew's old audio lib for proof: https://github.com/andrewrk/libsoundio

How can I record and cut a sound in c++
http://libsound.io is a great cross platform library for reading and writing to sound cards. i have used it successfully on macos and i’m sure it supports linux and possibly windows too. you will probably also need lib audio for reading and writing to files.

Learn Enough C to Survive
Hmm... after some research it seems that I've misunderstood Zig's situation a bit. Zig has introduced null-terminated string types a couple of years ago, but still encourages you to do most string operations with slices instead. Let me explain:
Zig's string literals (which you create with parenthesis like "Hello world!") are null-terminated byte arrays, expressed as the type const [N:0]u8 (where the :0 tells you that it's null-terminated), whereas the more typical array might be written as const [N]u8. The reason for this feature is not because the language wants you to use null-terminated strings, but because these static strings need to be stored in the global data section of the ELF executable, and these require you to use null-termination. But if you want to do any mutable operation with this string, you need to convert this into a proper slice (ptr + size). And it seems like Zig developers don't really use null-terminated types that much at the API level, but use it for things like C interop or cases where you really need it for special optimizations.
Noting that from the PR that introduced this feature, Andrew Kelley writes:
> I think you will find that the Zig community in general (and especially myself) agrees with you on this [null-terminated strings being fragile], and APIs in general should prefer slices to null terminated pointers. Even if you are using Zig to create a C library, and even in actual C libraries, I would recommend pointer and length arguments rather than null terminated pointers, like this: https://github.com/andrewrk/libsoundio/blob/1.1.0/soundio/so...
> That being said, I want to repeat what I said earlier about null terminated pointers: A null terminated array is not inherently an evil C concept that is intruding in the Zig language. It's a general data storage technique that is valid for some memory constrained use cases. I also stumbled on a Real Actual Use Case inside LLVM. The bottom line for me is that null terminated pointers exist in the real world, and especially in systems programming. You can see this in interfaces with the operating system in the standard library...
So he acknowledges null-terminated strings can certainly be useful in certain situations outside of legacy reasons, which is good to know. And Zig creating a special type for this shows that a good systems language needs to be designed to accommodate the needs of the outside world.

Ask HN: Cross platform method for accessing system audio output?
Perhaps you could use either http://libsound.io/ or SDL2 game library + SDLAudioIn (http://burningsmell.org/sdl_audioin/) which provides low-level APIs to access operating-system sound systems like Alsa, PulseAudio, PipeWire, and CoreAudio (not sure how well it is supported by SDL2).

Is programming truly for me?
Fun fact: Andrew Kelley, the creator of the Zig programming language, kind of created it so he could work on audio processing.

libsoundio: why does one sine play without cuts, but adding another or more produces periodic-like clicks?

Jam live with your friends with Svelte!
I listened to the Co-recursive podcast the other day that featured Andrew Kelley, the creator of the Zig programming language. Before Zig he developed Libsoundio - https://github.com/andrewrk/Libsoundio, to solve problems around realtime audio.

Mach Engine: The future of graphics (with Zig)
Audio will probably come later, but libsoundio will be the first thing in terms of groundwork. Integrating that in the same way we've integrated GLFW, so you can just cross compile and get cross-platform audio to boot.

What is the fastest way to encode the arbitrary struct into bytes?
so appreciate such a detailed reply, thanks. btw, why did you choose tinylib/msgp from 4 available go-impls?

Using Arduino as input to Rust project (help needed)
If you find you're running the serial connection at maximum speed and it's still not fast enough, try switching to a more compact binary encoding that has both Serde and Arduino implementations, like MsgPack... though I don't remember enough about its format off the top of my head to tell you the easiest way to put an unambiguous header on each packet/message to make the protocol self-synchronizing.

Java Serialization with Protocol Buffers
The information can be stored in a database or as files, serialized in a standard format and with a schema agreed with your Data Engineering team. Depending on your information and requirements, it can be as simple as CSV, XML or JSON, or Big Data formats such as Parquet, Avro, ORC, Arrow, or message serialization formats like Protocol Buffers, FlatBuffers, MessagePack, Thrift, or Cap'n Proto.

Multiplayer Networking Solutions
MessagePack Similar to JSONs, just more compact, although not as much as the ones above. Still, it's usefull to retain some readability in your messages.

GitHub - realtimetech-solution/opack: Fast object or data serialize and deserialize library
First of all, you're comparing this to GSON and Kryo, how does it compare to Msgpack, fast-serialization, but also Elsa and I'm sure, many others? Are there any limitations and/or trade-offs?

Optimal dispatcher for json messages ?
Upvote for msgpack, one of the great undervalued message protocols available.

Rust is just as fast as C/C++
I have two suggestions Capnproto, MessagePack (those are only the two examples that came to mind first, i bet there are even one or two especially developed for rust). Both of these are better than json in nearly every way.
