Audio playback and recording for Python

github.com/spatialaudio/python-sounddevice ↗

A stable audio I/O binding whose entire recent history is Windows on ARM.

audioportaudiopython-bindingswindows-arm64packaging
◆Current state
python-sounddevice binds PortAudio for NumPy-based audio recording and playback in Python. The API is settled; the visible release history is a sequence of single-line changes, and the last three of them exist because of Windows ARM64 — first providing wheels for it, then fixing what that broke, then fixing architecture detection on the same platform.
◆Where it's heading
The package is in a phase where platform packaging, not functionality, drives releases. The only capability change in the visible window is explicit_sample_format on WasapiSettings, a Windows-specific option. Combined with the earlier ASIO DLL bundling, the pattern is clear: the maintenance surface is Windows audio backends and the wheel matrix, while the cross-platform core sits untouched.
◆Prediction
Expect further packaging-level releases as the Windows ARM64 wheel path settles. Nothing in these entries suggests API work is planned.

◆Recent moves

    Windows ARM64 architecture detection fixed

    Fixes architecture detection on Windows ARM64, the third consecutive release dealing with that platform. A packaging correction, not an API change.

    Patch for regression in the previous release

    A same-week patch for a bug introduced by the previous release, with the body offering no further detail. The immediate follow-up to the ARM64 wheel addition two days earlier.

    Wheels published for ARM64 Windows

    Provides wheels for ARM64 Windows, meaning users on that platform install from a binary rather than needing a build toolchain. The two releases that follow are both consequences of this one.

    explicit_sample_format added to WasapiSettings

    Adds explicit_sample_format to WasapiSettings, giving callers direct control over sample format negotiation on the Windows WASAPI backend. The only functional API addition in the visible history.

    Clearer error for non-integer frames or channels

    Improves the error raised when frames or channels are passed as non-integers. A diagnostics touch-up on an easy caller mistake.

    Windows wheels bundle ASIO and non-ASIO DLLs

    Windows wheels bundle both ASIO and non-ASIO PortAudio DLLs, selectable at runtime through the SD_ENABLE_ASIO environment variable. Low-latency ASIO access previously required building PortAudio yourself.
