Whether you want to fix a previously recorded bad recording, restore some old demos, or remove some annoying noise from the recording, this article will give you some help.
repair
If there are obvious errors in the vocal part of your recording (such as singing or pronouncing the wrong lyrics), sometimes you may not necessarily have to go to great lengths to repair them. You can use similar syllables in other sentences in the song to replace the incorrect parts. For example, in the climax of a song, there will always be repeated sentences, right?
Your digital audio workstation has the functions of copying, pasting, proofreading, and fine-tuning audio, so all of this can be tried. Note that many consonants in human voice (such as T, C, P, K, and S) have no pitch, so you don't need to adjust them (this is mainly for most Western language families). You can get these consonants in many places in a song and use them to patch up the wrong parts.
match
If you haven't adjusted a relatively "matching" balance, you can use two spectrum analyzers. One is loaded onto the track you want to simulate, and the other is loaded onto the track you want to adjust. Follow the instructions on the spectrum analyzer to simulate the track you want to adjust. The best thing is that some equalization plugins provide multi-channel input, allowing you to see the overlapping equalization curves of two tracks on the same display screen in real time and compare them. Alternatively, if the equalization plugin supports stereo mode, you can also adjust the two tracks to extreme right and extreme left for comparison.
noise reduction
If you use a denoising device like iZotope's RX2 Denoiser, make sure to place it at the forefront of any compression class effects in the effects chain. This is because the compression effect device will increase the background noise in the audio and affect the dynamics of the background noise. As a result, if the noise reducer is placed after the compression effect device, the sound will become more difficult to process in the subsequent down mixing process.
Using triggers
Nowadays, we often see the use of drum triggers, but why not use triggers from other instruments? Most digital audio workstations now have the function of converting audio to MIDI signals for instruments with pitch. When you are facing a very challenging audio processing problem, this may be a very feasible solution. You just need to make simple adjustments to the MIDI section and select a high-quality virtual instrument.
For polyphonic chord transitions, we recommend that you take a look at Celebrity's Melody. Alternatively, you can simply rely on manual editing for re editing. Although it may take up a lot of your time, it is still more efficient compared to re recording audio tracks that you cannot record well no matter how hard you try.
Turn off the rhythm ruler
In actual recording work, musicians usually play along with the beat of the drum, and even if the drummer records it himself, he may not accurately aim at the metronome when playing. So if you only quantify drums or other single instruments, then you may erase the overall rhythm of the music.
Rhythm timing
Our sample recordings usually come with metronome markers to help us better edit the audio. If the instruments or vocals in the audio you are editing are not played or sung at the same speed, you may need to spend some time creating a Temp Map before editing it. Some digital audio workstations have tools to assist with this operation, or to build a new Map to analyze the selected audio.
Make them jump
When you have re edited or adjusted an audio through some plugins, you can consider generating a new audio file and importing it into the project to avoid unnecessary clutter and confusion. You can delete the original track (of course, you can also backup it), or mute it, and if necessary, disable its plugins.
special tool
There are some great specialized tools on the market now for repairing and restoring abnormal audio recordings. Zynaptiq's Unveil and Unfilter allow you to remove individual reverbs and abnormal spectral responses from audio signals. And both Melody from Celemony and AutoTune from Antares allow you to adjust the pitch/duration in the audio.
Clarify one's own limitations
There will always be something that limits your ability to make sound better, so don't be crazy about making your music exactly like your favorite commercial works. In fact, recognizing some of the quirky parts in your audio and making it sound more distinctive is the best.
Live performance is the key
If you have the opportunity to record your voice better, then you must do so! But remember: excellent playing skills and average sound quality are better than average playing skills and excellent sound quality.
Give a good example: The vocals in Christina Aguilera's "Beautiful" are recorded very raw and rough, even like a small sample. This kind of voice with primitive emotions is difficult to achieve in post production, so the producer did not hesitate to use a sample version as the official version.
