Detailed Description

Implements a discord voice connection. Each discord_voice_client connects to one voice channel and derives from a websocket client.

Member Enumeration Documentation

◆ send_audio_type_t

The audio type to be sent.

Note
On Windows, the default type is overlap audio. On all other platforms, it is recorded audio.

If the audio is recorded, the sending of audio packets is throttled. Otherwise, if the audio is live, the sending is not throttled.

Discord voice engine is expecting audio data as if they were from some audio device, e.g. microphone, where the data become available as they get captured from the audio device.

In case of recorded audio, unlike from a device, the audio data are usually instantly available in large chunks. Throttling is needed to simulate audio data coming from an audio device. In case of live audio, the throttling is by nature, so no extra throttling is needed.

Using live audio mode for recorded audio can cause Discord to skip audio data because Discord does not expect to receive, say, 3 minutes' worth of audio data in 1 second.

There are some inaccuracies in the throttling method used by the recorded audio mode on some systems (mainly Windows) which causes gaps and stutters in the resulting audio stream. The overlap audio mode provides a different implementation that fixes the issue. This method is slightly more CPU intensive, and should only be used if you encounter issues with recorded audio on your system.

Use discord_voice_client::set_send_audio_type to change this value as it ensures thread safety.

◆ send_audio_opus() [1/2]

discord_voice_client& dpp::discord_voice_client::send_audio_opus ( uint8_t *  opus_packet,
const size_t  length 
)

Send opus packets to the voice channel.

Some containers such as .ogg may contain OPUS encoded data already. In this case, we don't need to encode the frames using opus here. We can bypass the codec, only applying libsodium to the stream.

Duration is calculated internally

Parameters
opus_packetOpus packets. Discord expects opus frames to be encoded at 48000Hz
lengthThe length of the audio data.
Returns
discord_voice_client& Reference to self
Note
It is your responsibility to ensure that packets of data sent to send_audio are correctly repacketized for streaming, e.g. that audio frames are not too large or contain an incorrect format. Discord will still expect the same frequency and bit width of audio and the same signedness.
Exceptions
dpp::voice_exceptionIf data length is invalid or voice support not compiled into D++

◆ send_audio_opus() [2/2]

discord_voice_client& dpp::discord_voice_client::send_audio_opus ( uint8_t *  opus_packet,
const size_t  length,
uint64_t  duration 
)

Send opus packets to the voice channel.

Some containers such as .ogg may contain OPUS encoded data already. In this case, we don't need to encode the frames using opus here. We can bypass the codec, only applying libsodium to the stream.

Parameters
opus_packetOpus packets. Discord expects opus frames to be encoded at 48000Hz
lengthThe length of the audio data.
durationGenerally duration is 2.5, 5, 10, 20, 40 or 60 if the timescale is 1000000 (1ms)
Returns
discord_voice_client& Reference to self
Note
It is your responsibility to ensure that packets of data sent to send_audio are correctly repacketized for streaming, e.g. that audio frames are not too large or contain an incorrect format. Discord will still expect the same frequency and bit width of audio and the same signedness.
Exceptions
dpp::voice_exceptionIf data length is invalid or voice support not compiled into D++

◆ send_audio_raw()

discord_voice_client& dpp::discord_voice_client::send_audio_raw ( uint16_t *  audio_data,
const size_t  length 
)

Send raw audio to the voice channel.

You should send an audio packet of send_audio_raw_max_length (11520) bytes. Note that this function can be costly as it has to opus encode the PCM audio on the fly, and also encrypt it with libsodium.

Note
Because this function encrypts and encodes packets before pushing them onto the output queue, if you have a complete stream ready to send and know its length it is advisable to call this method multiple times to enqueue the entire stream audio so that it is all encoded at once (unless you have set use_opus to false). Constantly calling this from dpp::cluster::on_voice_buffer_send can, and will, eat a TON of cpu!
Parameters
audio_dataRaw PCM audio data. Channels are interleaved, with each channel's amplitude being a 16 bit value.
Warning
The audio data needs to be 48000Hz signed 16 bit audio, otherwise, the audio will come through incorrectly!
Parameters
lengthThe length of the audio data. The length should be a multiple of 4 (2x 16 bit stereo channels) with a maximum length of send_audio_raw_max_length, which is a complete opus frame at highest quality.

Generally when you're streaming and you know there will be more packet to come you should always provide packet data with length of send_audio_raw_max_length. Silence packet will be appended if length is less than send_audio_raw_max_length as discord expects to receive such specific packet size. This can cause gaps in your stream resulting in distorted audio if you have more packet to send later on.

Returns
discord_voice_client& Reference to self
Exceptions
dpp::voice_exceptionIf data length is invalid or voice support not compiled into D++

◆ send_close_packet()

void dpp::websocket_client::send_close_packet ( )
inherited

Send OP_CLOSE error code 1000 to the other side of the connection. This indicates graceful close.

◆ send_silence()

discord_voice_client& dpp::discord_voice_client::send_silence ( const uint64_t  duration)

Send silence to the voice channel.

Parameters
durationHow long to send silence for. With the standard timescale this is in milliseconds. Allowed values are 2.5, 5, 10, 20, 40 or 60 milliseconds.
Returns
discord_voice_client& Reference to self
Exceptions
dpp::voice_exceptionif voice support is not compiled into D++

◆ set_iteration_interval()

discord_voice_client& dpp::discord_voice_client::set_iteration_interval ( uint16_t  interval)

Change the iteration interval time.

Parameters
timeThe time (in milliseconds) between each interval when parsing audio.
Returns

Sets the audio type that will be sent with send_audio_* methods.

See also
send_audio_type_t

◆ set_timescale()

discord_voice_client& dpp::discord_voice_client::set_timescale ( uint64_t  new_timescale)

Set the timescale in nanoseconds.

Parameters
new_timescaleTimescale to set. This defaults to 1000000, which means 1 millisecond.
Returns
discord_voice_client& Reference to self
Exceptions
dpp::voice_exceptionIf data length is invalid or voice support not compiled into D++

◆ set_user_gain()

void dpp::discord_voice_client::set_user_gain ( snowflake  user_id,
float  factor 
)

Sets the gain for the specified user.

Similar to the User Volume slider, controls the listening volume per user. Uses native Opus gain control, so clients don't have to perform extra audio processing.

The gain setting will affect the both individual and combined voice audio.

The gain value can also be set even before the user connects to the voice channel.

Parameters
user_idThe ID of the user where the gain is to be controlled.
factorNonnegative factor to scale the amplitude by, where 1.f reverts to the default volume.

◆ skip_to_next_marker()

discord_voice_client& dpp::discord_voice_client::skip_to_next_marker ( )

Skip tp the next track marker, previously inserted by using the dpp::discord_voice_client::insert_marker function. If there are no markers in the output buffer, then this skips to the end of the buffer and is equivalent to the dpp::discord_voice_client::stop_audio function.

Note
It is possible to use this function while the output stream is paused.
Returns
reference to self

◆ speak()

discord_voice_client& dpp::discord_voice_client::speak ( )

Mark the voice connection as 'speaking'. This sends a JSON message to the voice websocket which tells discord that the user is speaking. The library automatically calls this for you whenever you send audio.

Returns
