Get the human-readable name of a specific audio device.


const char* SDL_GetAudioDeviceName(int index,
                                   int iscapture);

Function Parameters

index the index of the audio device; valid values range from 0 to SDL_GetNumAudioDevices() - 1
iscapture non-zero to query the list of recording devices, zero to query the list of output devices.

Return Value

Returns the name of the audio device at the requested index, or NULL on error.


This function is only valid after successfully initializing the audio subsystem. The values returned by this function reflect the latest call to SDL_GetNumAudioDevices(); re-call that function to redetect available hardware.

The string returned by this function is UTF-8 encoded, read-only, and managed internally. You are not to free it. If you need to keep the string for any length of time, you should make your own copy of it, as it will be invalid next time any of several other SDL functions are called.


This function is available since SDL 3.0.0.

Code Examples

int i, count = SDL_GetNumAudioDevices(0);

for (i = 0; i < count; ++i) {
    SDL_Log("Audio device %d: %s", i, SDL_GetAudioDeviceName(i, 0));
