The ability to pitch-shift audio and time-stretch loops to fit a given tempo is a standard feature and one for which Ableton Live was invented. This looping technique has been adopted by pretty much every audio production program since. Armed with a sample CD of 'Acidized' loops, you could paint them onto a timeline and pull together arrangements at great speed. Loops in ACID contained tempo and key information that allowed them to be matched automatically when used in the same project. When it first appeared in the late '90s, ACID's extraordinary ability to manipulate the pitch and tempo of looped audio created a whole genre of computer-based loop sequencing that had previously been the realm of scratch DJs and hardware samplers. Repeat steps 2 through 4 to choose an input device and set levels for each track.Ĭlick the Record button below the timeline when you’re ready to start recording.įor more information about recording audio, please see Recording Audio.ACID Pro is the original loop-based remixing program, and the Next version opens up new possibilities thanks to the intriguing Stem Maker.

If you have a sound card with multiple inputs and outputs, you can record multiple tracks at once. Select (or unmute) the device from which you want to record.Īdjust the Volume faders for the selected device and for the Master Record level while monitoring the recording meters in the ACID Record dialog.įor example, if you want to record from an audio CD in your CD-ROM drive, the CD Mute check box should not be selected, and the CD and Master Record Volume faders must be adjusted so ACID receives a strong signal with no clipping.
ACID PRO STUDIO WINDOWS
If you’re using your Windows sound card, perform the following steps to open the recording controls:ĭouble-click the speaker icon in your system tray to open the Volume Control window.įrom the Options menu, choose Properties.Ĭlick the Recording radio button and click OK. Adjust the gain controls in the console application so ACID receives a strong signal with no clipping.įor more information about using your sound card and its console application, please refer to the manufacturer’s documentation. If your audio device provides a console application to adjust levels, open the application and adjust its gain controls while monitoring the peak meters on the Meters tab in the recording dialog. To choose your recording input, click the Record Device Selector button, choose an audio device from the menu, choose Mono or Stereo from the submenu, and then choose an input. Dashed lines represent a sync connection from your audio source to a MIDI timecode converter to a MIDI card. In this setup, an audio source with digital input/output is connected to a sound card with digital input and outputs. A phono preamplifier will convert the phono-level signal to a line-level signal that you can record.ĭigital input/output with MIDI synchronization

Phono-level outputs are quieter than line-level outputs and have special equalization applied. Most turntables’ outputs are phono-level (rather than line-level) outputs. If you’re recording from a turntable, use a phono preamplifier between your turntable’s output and your sound card’s line input. The mixer/preamplifier is then connected to Line In and Line Out connections on your sound card. In this setup, your speakers and audio source are connected to a mixer or preamplifier. You could connect a computer microphone to your sound card’s Mic In input, or you can connect line-level outputs from a tape deck or other source to a Line In input. In this setup, an audio source is connected to an input on your sound card, and your powered speakers are connected to a Line Out output.
