Re-amping is a process often used in multitrack recording in which a recorded signal is routed back out of the editing environment and run through external processing or reverb chamber. Originally, the technique was used mostly for guitars: it facilitates a separation of guitar playing from guitar amplifier processing—a previously recorded audio program is played back and re-recorded at a later time for the purpose of adding effects, ambiance, or modified tonality. The technique has since evolved to include many other applications. Re-amping can also be applied to other instruments and program, such as recorded drums, synthesizers, and virtual instruments. Examples of common re-amping objectives include musically useful amplifier distortion, room tone, compression, EQ/filters, envelopes, resonance, and gating. Re-amping is often used to "warm up" dry tracks, which often means adding complex, musically interesting compression, distortion, filtering, ambiance, and other pleasing effects. By playing a dry signal through a studio's main monitors and then using room mics to capture the ambiance, engineers are able to create realistic reverbs and blend the wet signal with the original dry recording to achieve the desired amount of depth. The technique is especially useful for softening stereo drum tracks. By pointing the monitors away from each other and miking each speaker individually, the stereo image can be well preserved and a new depth can be added to the track. It is important to check that the microphones being used are in phase to avoid problems with the mix. == Example of re-amping == A guitarist records a dry, unprocessed, unaffected track in a recording studio. This is often achieved by connecting the guitar into a DI unit (a Direct Input or Direct Inject buffer box) that is fed to a recording console or, alternatively, bypassing the console by using an outboard preamplifier. Often, the guitarist's signal is sent to both recorder and guitar amp simultaneously, providing the guitarist with a proper amplifier "feel" while also tracking a dry signal. At a later time, the dry, direct, unprocessed guitar recording is fed to a bridging device (a Reamp or reverse DI box) to "re-record" the guitarist's unprocessed performance through a dedicated guitar amplifier and/or external effects box(es). The guitar amplifier is placed in the live room or isolation booth of the recording studio and is set up to produce the desired tonal quality, including distortion character and room reverberation. A microphone is placed near the guitar speaker and a new track is recorded, producing the re-amplified, processed track. The microphone cable is connected to the mixing console or mic preamp using a cable, as usual, without using a bridging device. External effects such as stomp boxes and guitar multi-fx processors can also be included in the re-amping process. As well as physical devices that require an impedance-matched guitar pickup signal, software-based virtual guitar effects and amps can be included in the re-amping process. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Re-amp」の詳細全文を読む スポンサード リンク
