DirectSound is designed as a single bit depth and sample rate method, this means verything that differs from the configured system resolution will get automatically resampled to match it. DirectSound by default is usually configured for 16bit 48KHz in most systems which negates any hypothetical benefit of higher bit depths or sampling rates.

If you want to get bit perfect as in no resampling or additional processing the best way is using any of the systems that avoid going through the Windows Mixer namely:. Not supported by all soundcards. It is a robust low latency way to get all the bits as close to the original as possible.

Similar performance to ASIO and broader compatibility. Notice separate values for Event and push mode are available see image below so adjust the one you are using.

Through the session abstraction, a WASAPI client can identify an audio stream as a member of a group of related audio streams. The system can manage all of the streams in the session as a single unit.

The audio engine is the user-mode audio component through which applications share access to an audio endpoint device. The audio engine transports audio data between an endpoint buffer and an endpoint device.

To play an audio stream through a rendering endpoint device, an application periodically writes audio data to a rendering endpoint buffer. The audio engine mixes the streams from the various applications. To record an audio stream from a capture endpoint device, an application periodically reads audio data from a capture endpoint buffer.

The first of these is the IAudioClient interface. The client calls the IAudioClient::Initialize method to initialize a stream on an endpoint device.

Frequently, the application can recover from this error. For more information, see Recovering from an Invalid-Device Error. WASAPI clients that require notification of session-related events should implement the following interface.

IAudioClient Enables a client to create and initialize an audio stream between an audio application and the audio engine or the hardware buffer of an audio endpoint device. IAudioClock Enables a client to monitor a stream's data rate and the current position in the stream. IAudioRenderClient Enables a client to write output data to a rendering endpoint buffer. IAudioSessionControl Enables a client to configure the control parameters for an audio session and to monitor events in the session.This page describes how to set up audio for the Windows OS.

Kodi uses WASAPI only in the Exclusive Mode of operation in order that Kodi gets the exclusive rights to the audio buffers whilst playing audio streams to the exclusion of all other sounds or players, this is a change from previous version of Kodi where Shared Mode was also allowed.

If this driver is not installed then the HD formats will be missing from the Supported Formats tab. Step 1: Select Device Manager then go to Sound, video and game controllers.

Select the device you'll be using for audio and right click then select Properties. Step 2: Go to Driver tab and ensure Driver Provider shows the manufacturer of your device.

If Microsoft is shown here then you have a driver provided by your Windows installation or Windows Update. In the case of HDMI being used to provide audio, you must ensure the driver is provided by your device manufacturer as the Microsoft provided ones will usually have reduced functionality such as HD Audio formats not supported.

Step 4: Next launch the Configure wizard to set the speaker layout you have. In this tab you'll see the formats that the audio driver is reporting to Windows that you selected hardware is capable of, if audio codecs are missing from Encoded Formats list then Kodi won't be able to play these formats back.

If formats are missing that you know your hardware is capable of then this points to there being either a driver problem or if using HDMI then it maybe a EDID handshaking problem. Step 6: Finally go to the Advanced Tab and ensure the Exclusive Mode check boxes Allow applications to take exclusive control of this device and Give exclusive mode applications priority are ticked.

Once this is done you should be good to go in setting up audio on Kodi so refer back to AudioEngine. DirectSound acts as a program-friendly middle layer between the program and the audio driver, which in turn speaks to the audio hardware.

With DirectSound, Windows controls the sample rate, channel layout and other details of the audio stream via an Audio Mixer. Every program using sound passes it's data to DirectSound and the Audio Mixer which then resamples as required so it can mix audio streams from any program together with system sounds. The advantages are that programs don't need resampling code or other complexities, and any program can play sounds at the same time as others, or the same time as system sounds, because they are all mixed to one format.

The disadvantages are that other programs can play at the same time, and that a program's output gets mixed to whatever the system's settings are. This means the program cannot control the sampling rate, channel count, format, etc. Even more important for this thread is that you cannot pass through encoded formats, as DirectSound will not decode them and it would otherwise bit-mangle them, and there is a loss of sonic quality involved in the mixing and resampling.

Shared mode is in many ways similar to DirectSound as it allows other sounds to be mixed into the currently playing stream, however this mode is not supported on Kodi so won't be covered any further here. WASAPI Exclusive mode allows the application to interrogate the capabilities of the audio driver, since audio is presented directly by the application to the audio driver the format that the audio is sent in by the application must be in a format that is compatible with the capabilities of the audio driver, as there is no DirectSound between to convert it.

This interrogation is a two way process that often involves some back-and-forth depending on the format specified and the device's capabilities, once a set of compatible formats is agreed upon by application and audio driver, the application then decides how it will present the audio stream to the audio driver.

In addition to Shared and Exclusive modes, there are two modes for how data is passed from the application to the audio driver. The normal manner is in push mode - a buffer is created which the audio device draws from, and the application pushes as much data in as it can to keep that buffer full.

To do this it must constantly monitor the levels in the buffer, with short "sleeps" in between to allow other threads to run. In this mode two buffers are used.Following the acquisition of certain assets and the complete set of intellectual property of Cakewalk Inc.

If I remember correctly the article you quoted said 15ms lower latency placing it near to that of ASIO. I am not experiencing any dropoutsclicks or pops during payback. I do not plan to upgrade to Windows 10 at this time This may change in the medium future.

I have used it myself and the latency in low level projects is pretty decent. But ASIO it is not. That is almost at the point of "not usable for live performance using soft synths". Doktor Avalanche. Max Output Level: Unless the driver is dodgy always use ASIO. ASIO bypasses a few layers so performance should be better. I have some projects running as low as 2.

Thank you, Doktor, I think that "puts it to bed". The only thing I'd add is that a Microsoft representative implied they would continue work on lowering Windows native latency and hope it will be equivalent to ASIO eventually. Anderton The only thing I'd add is that a Microsoft representative implied they would continue work on lowering Windows native latency and hope it will be equivalent to ASIO eventually.

They'd have to punch out a few layers to match ASIO, maybe very near but I doubt they will match it unless they create a brand new format.It covers API options for application developers as well as changes in drivers that can be made to support low latency audio.

Audio latency is the delay between that time that sound is created and when it is heard. Having low audio latency is very important for several key scenarios, such as the following. Delay between the time that an application submits a buffer of audio data to the render APIs, until the time that it is heard from the speakers. Delay between the time that a sound is captured from the microphone, until the time that it is sent to the capture APIs that are being used by the application.

What are ASIO and WASAPI ?

Delay between the time that a sound is captured from the microphone, processed by the application and submitted by the application for rendering to the speakers. Delay between the time that a user taps the screen until the time that the signal is sent to the application. Delay between the time that a user taps the screen, the event goes to the application and a sound is heard via the speakers. The Audio Engine reads the data from the buffer and processes it. Starting with Windows 10, the buffer size is defined by the audio driver more details on this are described later in this topic.

Starting with Windows 10, the buffer size is defined by the audio driver more details on this below. The Audio Engine reads the data from the buffer and processes them. The application is signaled that data is available to be read, as soon as the audio engine finishes with its processing. The audio stack also provides the option of Exclusive Mode.

In that case, the data bypasses the Audio Engine and goes directly from the application to the buffer where the driver reads it from. However, if an application opens an endpoint in Exclusive Mode, then there is no other application that can use that endpoint to render or capture audio.

However, the application has to be written in such a way that it talks directly to the ASIO driver. Both alternatives exclusive mode and ASIO have their own limitations. They provide low latency, but they have their own limitations some of which were described above. As a result, Audio Engine has been modified, in order to lower the latency, while retaining the flexibility. The measurement tools section of this topic, shows specific measurements from a Haswell system using the inbox HDAudio driver.

The following sections will explain the low latency capabilities in each API. As it was noted in the previous section, in order for the system to achieve the minimum latency, it needs to have updated drivers that support small buffer sizes. This property can any of the following values shown in the table below:. Sets the buffer size to be either equal either to the value defined by the DesiredSamplesPerQuantum property or to a value that is as close to DesiredSamplesPerQuantum as is supported by the driver.

The following code snippet shows how to set the minimum buffer size:. The above features will be available on all Windows devices. However, certain devices with enough resources and updated drivers will provide a better user experience than others. IAudioClient3 defines the following 3 methods:. The following code snippet shows how a music creation app can operate in the lowest latency setting that is supported by the system. This will allow the OS to manage them in a way that will avoid interference non-audio subsystems.

In contrast, all AudioGraph threads are automatically managed correctly by the OS.These indications are the listing by the Qobuz application of the sound cards and DACs whose drivers are installed on your computer, even if they are not connected.

You will have to either plug it in or turn it back on. The Qobuz application offers four playback modes that we will enumerate by qualitative order, so to speak, before going into details:. It connects the kernel mixer, a part of the operating system that acts as an interface between the several audio sources of a PC PC sounds, MIDI, software players, etc.

As the different audio sources can produce sounds at different sampling frequencies, the kernel mixer is programmed to resample the diverse audio flows into one and one only sampling frequency, in order to mix them before directing them to the sound card. Unfortunately, this unique sampling frequency is generally low, typically Furthermore, the kernel mixer allows different processes dynamic compression, tone control, loudness control, spatialization effects… which are not clearly visible by the user, and cannot even be excluded.

We actually talk about bit-perfect playback when the digital audio file is kept fully intact in its original form, bit for bit, which guarantees that the sound card or the DAC will decode the file as it is natively if they also process it natively, which is not the case if there is a sampling rate conversion. The three other modes available in the Qobuz application are all bit-perfect.
