Since there is no amplification available, clipping is impossible on the outgoing signal. The highest level setting on the faders is 0dB, or Unity Gain, which is an easy way of indicating a gain of factor 1 (equivalent to 0dB) where both input and output are at the same voltage level and impedance.
To preserve a stereo signal coming into 2 hardware inputs - "H/W In 1/2", for example - mute the right fader on "H/W In 1", and mute the left fader on "H/W In 2." To pan soft right, set the right fader higher than the left. For example, to pan hard left, mute the right channel. The mute buttons do exactly what you would expect: they mute the outgoing channel.Ī mono signal can be panned by setting the stereo faders or mute controls accordingly. A pair of faders can be "ganged", so that both channels can be controlled as a stereo pair. They do not control the level of the incoming audio signals - they are "post-meter." There is no gain control the faders can only attenuate (reduce) the signal levels. The faders control the signal level in the card's digital mix. Adjust the output level of your audio source along with the appropriate "ADC" faders on the "Analog Volume" page so that the incoming audio levels do not peak in the red very often or for too long. The red zone represents danger when the signal hits 0dB, overload and audio clipping may occur. The orange section represents a hotter zone it is both safe and recommended to adjust the incoming signal to meter mostly in this zone when recording. The green section is a safe zone most incoming audio signals should fill at least this section of the meter when recording. Each input's meters are color-coded into three sections: green, orange, and red. "H/W OUT 1/2.")Įach mixer input channel has its own level meter that indicates the "pre-fader" levels of the incoming audio signal and are therefore not affected by the fader settings. On the far left, there is a meter indicating the overall signal level being routed to the on-board mixer's "pre out." The output of this digital mixer may be assigned to any of your card's hardware outputs on the Patchbay /Router page, by selecting "Digital Mix L/R." (Typically, you would do this for the hardware outputs that your monitor speakers are connected to, e.g. For each physical card input, there is a pair of volume faders, mute buttons, and pre-fader level meters. It enables you to meter the "post-gain" incoming audio signals and adjust their volumes in the card's on-board "monitor" mixer. The Monitor Inputs page is effectively a mixer for your card's hardware inputs. Save yourself some frustration: read the manual. It is more likely to do just the opposite.
If you do not, envy24control will not make working with the card any clearer or easier.
It is vital that you understand your sound card's features and capabilities.
ARDOUR FOR LINUX SOFTWARE
This mixer accepts digital audio streams from hardware inputs and outgoing streams from software audio devices (such as those provided by JACK), mixes them internally, and then sends the mixed output to the card's hardware outputs. If you have one of the cards in the list above, know that it has a hardware digital audio mixer built into it (the Ice1712 chip). Supported cardsĮnvy24control is designed to control ice1712-based cards, including, but not limited to: It is identical to envy24control, except that it has some clearer UI labels, peak meter indicators, and a few other bells and whistles. Note: mudita24-git AUR is an alternative to envy24control available in the AUR.
