Windows wasapi

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>>">

#1 I didn't manage to find any discussions on this (I'm sure there has been), so thought I'd ask myself.The general consensus on Windows volume control seems to be that it should be left at 100% because messing with it introduces conversion errors, please correct if that statement is wrong.How does adjusting the preamp setting in e.g. EQ APO Peace plugin to a negative value differ from adjusting the windows volume down from 100%? #2 Leave the Windows volume at 100% to send a strong signal to whatever device your sending audio to.Use something with WASAPI to keep the signal clean. #3 The general consensus on Windows volume control seems to be that it should be left at 100% because messing with it introduces conversion errors, please correct if that statement is wrong. I think the real consensus is to not use Windows VC at all. Go Wasapi or ASIO. Thread Starter #4 Leave the Windows volume at 100% to send a strong signal to whatever device your sending audio to.Use something with WASAPI to keep the signal clean. I think the real consensus is to not use Windows VC at all. Go Wasapi or ASIO. Not a good option for me since I use Spotify a lot and there's no official support for Wasapi or ASIO in it.And there's plenty of people here using EQ APO etc, I've just assumed that you wouldn't use Wasapi/ASIO in that case since it kinda goes against the whole idea of direct sound

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,

Fix/debug the issue:* restart MusicBeeYou don't mention the one (most important) step to try: have you restarted Windows? They will free what whatever else is tying up WASPI. As with most Windows issues, restarting the OS should typically be the first troubleshooting step. Download the latest MusicBee v3.5 or 3.6 patch from here.Unzip into your MusicBee directory and overwrite existing files.----------The FAQThe WikiCustom Forum SearchPosting screenshots is here You don't mention the one (most important) step to try: have you restarted Windows? They will free what whatever else is tying up WASPI. As with most Windows issues, restarting the OS should typically be the first troubleshooting step.Yes, I forgot to mention that. I have restarted Windows many times and I have also tried plugging the DAC into different USB ports, as well as restarting the DAC, to see if it was potentially hardware related.The symptoms in the OP point to something else using the device at the time although that usually results in an error message for me.Definitely not the case. I used to use exclusive mode with MusicBee and another external DAC, so it's strange that MusicBee doesn't work with this one. But I am familiar with the process of using exclusive mode and all its quirks so I am definitely certain that no other device is grabbing the DAC. There isn't any other software configured to use exclusive mode on it, besides Foobar2000, which I only ran briefly yesterday to see if it was MusicBee or systemwide. Switching to WASAPI shared in MusicBee plays music through the DAC, which wouldn't be the case if another device was grabbing it. Switching to WASAPI shared in MusicBee plays music through the DAC, which wouldn't be the case if another device was grabbing it.Yes it would be the case. That's the whole point of WASAPI shared. Switching to WASAPI shared in MusicBee plays music through the DAC, which wouldn't be the case if another device was grabbing it.Yes it would be the case. That's the whole point of WASAPI shared.I mean that if another piece of software was using WASAPI exclusive on the DAC and actively playing back media, then MusicBee would be unable to play when set to WASAPI shared, at least until the device was released by the other software.
