Wasapi audio

WASAPI (Windows Audio Session API) is Microsoft’s multi-channel audio interface for communication with audio devices. WASAPI was introduced with Windows Vista™ and is supported by Windows 7 and later versions. WASAPI delivers an unmodified audio-stream to a sound device, and provides similar benefits as ASIO.The Windows Audio Session API is Microsoft's high-end method for interacting with audio devices. It was introduced with Windows Vista and is available in later versions of Windows.How does WASAPI work?WASAPI enables client applications, such as WATCHOUT, or any application using audio, to control the flow of audio between the application and audio playback devices. It allows delivery of an unmodified bit-stream to a sound device.WASAPI provides exclusive access to the audio devices, bypassing the system mixer, default settings, and any effects provided by the audio driver. Unless your audio interface has an ASIO driver, WASAPI is the recommended Audio Output Mode for Windows. WASAPI replaces all Microsoft Windows legacy output modes including Kernel Streaming and Direct Sound.Source: >Download now>>">

A. Dropout reason code Table 95. Audio engine dropout reason codes Code Reason for dropout Potential preventative action 0 Unknown error or no dropout. 1 Audio processing took longer than the buffers allotted time slice. Increase the Buffer Size value in Edit > Preferences > Audio - Driver Settings. 2 Buffer underrun while processing or error writing record buffers. Possible CPU overload or driver malfunction. Increase latency and check disk status. 3 Driver did not request audio buffers for over DropoutMsec milliseconds. Possible driver overload. Increase audio latency. Increase the DropoutMsec variable value in AUD.ini (see AUD.INI), which lets you configure the tolerance time in milliseconds before dropping if the audio pump mechanism becomes starved (default is 250 ms). 4 WDM/MME/WASAPI output buffer not available for delivery to audio device. Increase the Buffers in Playback Queue value in Edit > Preferences > Audio - Driver Settings. 5 Disk reading overloaded and could not keep up with playback pump. Disk may be fragmented or too slow to read. Increase the Playback I/O Buffer Size value in Edit > Preferences > Audio - Sync and Caching. Defragment audio drive or compacting audio files by saving to a bundle and reloading may also help. 6 [Internal] Error filling disk playback buffer cache. Disk may be full condition or disk read error. Check disk status. 7 [Internal] Error reading from disk playback buffer cache. Possible memory corruption. Close and restart the application then reload the project. 8 Disk full or error writing record wave files. Make sure the disk is not read only and has sufficient free space. 9 Sequencer MIDI pump underrun. Increase the Prepare using n Millisecond Buffers value in Edit > Preferences > MIDI - Playback and Recording. 10 [Internal] Audio pump frequency problem. 11 [Internal] Unexpected error while processing audio buffer. Try saving then closing and reopening the project. 12 [Internal] Internal audio buffer memory limit overflow. Contact support with recipe/project file. 13 ASIO subsystem signaled a dropout due to a state change. Don’t make changes to ASIO driver during playback. Another app may be using driver. 14 [Internal] WASAPI ReadDataBuffer timed out. WASAPI device error - restart device or close other applications using it. 15 [Internal] WASAPI buffer underrun. WASAPI device error - restart device or close other applications using it. 16 [Internal] WASAPI Read/Write buffer failed. WASAPI device error - restart device or close other applications using it.

Since Bandicam records sound from Windows system audio, DAW sounds using ASIO drivers that do not go through Windows cannot be recorded with Bandicam's default settings. In this case, you can record DAW sounds with Bandicam using a virtual audio mixer such as VoiceMeeter or the WASAPI driver that goes through Windows' normal audio path. [Method 1] How to record DAW sounds using virtual ASIO drivers [Method 2] How to record DAW sounds using WASAPI drivers Terms explanation DAWDAW (Digital Audio Workstation) refers to software used for recording, editing, playing, and producing audio files. Notable DAW software include FL Studio, Cakewalk, Cubase, etc. ASIOASIO (Audio Stream Input/Output) is a computer sound card driver protocol characterized by low audio latency, which enables DAW applications to connect directly to the sound card hardware. WASAPIWASAPI (Windows Audio Session API) is an audio API developed by Microsoft. WASAPI sharing mode allows sound to be played simultaneously in multiple devices or programs through the Windows audio path. How to record DAW sounds using virtual ASIO drivers VoiceMeeter is a virtual audio mixer program that can connect all the inputs of your ASIO interface to the Windows sound system. Using this VoiceMeeter program, you can record DAW sounds on Windows with Bandicam Screen Recorder. Install the Voicemeeter STANDARD or BANANA version. Select the VoiceMeeter driver in the audio settings of your DAW program. Cubase program example: Run the Cubase DAW program and select VoiceMeeter Virtual ASIO as the ASIO driver. Open the Voicemeeter program and select the input/output device. In [ HARDWARE INPUT 1 or 2 ], select the external device (microphone, instrument, etc.) to be recorded as the input device. In [ HARDWARE OUT ], select the Windows speaker device or audio interface as the output device. In Bandicam, select “(default output device)” or the device selected in HARDWARE OUT (number 2 in the picture above). If you set it up as above, you can record DAW sounds using Bandicam Screen Recorder on Windows. However, even if you follow the steps above, sound may not be recorded depending on the type of audio interface, DAW program settings, Windows audio settings, etc. How to record DAW sounds using WASAPI driver WASAPI is the audio API of Windows. If you set the audio driver that uses WASAPI sharing mode in the audio settings of the DAW software, you can record DAW sound with Bandicam. Representative DAW programs that support WASAPI are as follows: 1. FL Studio FL Studio is a digital audio workstation developed by the Belgian company Image-Line. If you select "FL Studio ASIO" in the Audio settings of FL Studio, you can record the sound of FL Studio with Bandicam. 2. Cakewalk Cakewalk by BandLab is a free DAW software for audio recording, arranging, editing, mixing, and mastering. If you select "WASAPI Shared" in Cakewalk - Preferences - Playback and Recording, you can record the sound of Cakewalk with Bandicam. 3. Cubase Cubase is a DAW developed by Steinberg for music and MIDI recording, arranging,
