 Major Features
@@ -136,45 +173,37 @@ Major Features
 - No external dependencies except for the C standard library and backend libraries.
 - Written in C and compilable as C++, enabling miniaudio to work on almost all compilers.
 - Supports all major desktop and mobile platforms, with multiple backends for maximum compatibility.
-- Supports custom backends.
+- A low level API with direct access to the raw audio data.
+- A high level API with resource management, node graphs and effects, including 3D spatialization.
+- Custom backends.
 - Supports playback, capture, full-duplex and loopback (WASAPI only).
 - Device enumeration for connecting to specific devices, not just defaults.
 - Connect to multiple devices at once.
 - Shared and exclusive mode on supported backends.
-- Backend-specific configuration options.
+- Data conversion (sample format, channel conversion and resampling).
-- Device capability querying.
-- Automatic data conversion between your application and the internal device.
-- Sample format conversion with optional dithering.
-- Channel conversion and channel mapping.
-- Resampling with support for multiple algorithms.
-  - Simple linear resampling with anti-aliasing.
-  - Optional Speex resampling (must opt-in).
 - Filters.
