wendy device audio listen
Stream raw audio from a device microphone
Syntax
wendy device audio listen [flags]Examples
wendy device audio listen --helpArguments
No positional arguments are declared in the command synopsis.
Flags
Flags below include inherited options. Types and defaults come from the CLI source. An empty default means no value is configured.
| Flag | Type | Default | Description |
|---|---|---|---|
--all | bool | false | Also offer unusable capture endpoints (HDMI/dummy/routing FIFOs); loopback mics are already auto-selected |
--buffer-ms | uint32 | 150 | Playback jitter-buffer target in ms; lower = less latency, more prone to dropouts |
--channels | uint32 | 1 | Number of audio channels |
--device | string | (empty) | Target device hostname; wendy run accepts a comma-separated list to deploy one build to several devices (needs a remote build host and --detach). Defaults to $WENDY_DEVICE, then the saved default device |
--id | uint32 | 0 | Audio device ID (default: auto-select or pick a microphone) |
--json | bool | false | Output in JSON format |
--non-interactive | bool | false | Disable terminal prompts and automatic updates; auto-select a usable microphone when --id is omitted |
--sample-rate | uint32 | 16000 | Sample rate in Hz |
--stdout | bool | false | Write raw PCM to stdout instead of playing |
Output
Output depends on the operation and selected target. Use the command help for additional guidance..
JSON output
The global --json option requests machine-readable output. The CLI also selects JSON mode when no interactive terminal is attached. Support and payloads are command-specific; this flag does not guarantee a single JSON document for commands that stream logs or invoke build tools. Consult Details before parsing command output.
Exit codes
The CLI entry point returns 0 on success and for its user-cancelled or default-cleared results. Other returned errors exit with 1 and print a diagnostic to stderr. Some operations may terminate through subprocess or signal handling; do not infer application health from the CLI exit code alone.
Common errors
Check argument values and flag combinations against the synopsis above. For discovery, build, port, and readiness failures, see deployment troubleshooting. Command-specific constraints are in Details.
