FOLLOW ME Instagram: this easy After Effects tutorial you will learn how to create a simple echo effect, using typ. Finally, we have the echo effects. To put it in the simplest way possible, an echo is a juxtaposition of the delay and reverb effects we’ve explored above. It gives you the space-expanding potential of the reverb and allows you to repeat notes like a delay. However, it can’t be classed as either of these effects and is one on. Jul 31, 2015 An echo can’t harm you. An echo doesn’t hurt and has no side effects. How do I prepare for the echo? You don’t have to do anything special. You can eat and drink before the test like you usually would. “While I was lying on my side, the technician asked me to move a little as he moved the wand around my chest.

Delay and echo effects

Adobe Audition has three echo effects with different capabilities. All delay effects store audio in memory and then play it back later. The time that elapses between storing it and playing it back is the delay time.

Delay

Delay simply repeats the audio, with the repeat’s start time specified by the delay amount.

1. Choose File > Close All. Don’t save any changes. Choose File > Open, navigate to the Lesson04 folder, and open the file Arpeggio110.wav.

2. Click an Effects Rack insert’s right arrow, and then choose Delay and Echo > Delay.

3. The Mix slider sets the proportion of dry and delayed audio. Set the Right Channel to full Dry and the Left channel to full Wet. This makes it easy to hear the difference between the delayed signal in the left channel and the dry signal in the right channel when the delay effect is enabled.

4. Set the left channel Delay Time slider full right (500ms). You’ll now hear the left channel arpeggio delayed by half a second compared to the right channel.
5. Set the left channel Delay Time slider full left (-500ms). You’ll now hear the arpeggio start half a second earlier in the left channel than in the right channel.
6. Set both Mix sliders to 50%, and experiment with different delay times. You’ll hear a mix of delayed and dry sounds in each channel. Leave the project open for the next lesson.

Analog Delay

Before digital technology, delay used tape or analog delay chip technology. These produced a grittier, more colored sound compared to digital delay. Audition’s Analog Delay provides a single delay for stereo or mono signals and offers three different delay modes: Tape (slight distortion), Tape/Tube (crisper version of tape), and Analog (more muffled). Analog Delay simply repeats the audio with the start time of the repeat specified by the delay amount. Unlike the Delay effect, there are separate controls for Dry and Wet levels instead of a single Mix control. The Delay slider provides the same function as the Delay effect except that the maximum delay time is eight seconds.

After Effects Posterize Time

1. Choose File > Close All. Don’t save any changes. Choose File > Open, navigate to the Lesson04 folder, and open the file Drums110.wav.
2. Click an Effects Rack insert’s right arrow, and then choose Delay and Echo > Analog Delay.
3. Set Dry Out to 60%, Wet Out to 40%, and Delay to 545ms. Feedback determines the number of repeats as they fade out. Start playback. No Feedback (a setting of 0) produces a single echo, values moving toward 100 produce more echoes, and values above 100 produce “runaway echoes” (watch your monitor volume!).
4. With feedback at 40, set the Trash control to 100. Change the different modes (Tape, Tape/Tube, Analog) to hear how each affects the sound. Vary the feedback, being careful to avoid excessive, runaway feedback.
5. Spread at 0% narrows the echoes to mono and at 200% produces a wide stereo effect. Play with the various controls, and you’ll hear anything from dance mix drum effects to 50s sci-fi movie sounds. Keep Audition open for the next lesson.

Echo

Audition’s Echo effect allows for tailoring the echoes’ frequency response by inserting a filter in the delay’s feedback loop, where the output feeds back to the input to create additional echoes. As a result, each successive echo processes each echo’s timbre to a greater degree. For example, if the response is set to be brighter than normal, each echo will be brighter than the previous one.

1. With the Drum110.wav file open, assuming the Analog Delay effect is still inserted and Audition is still playing, click its insert’s right arrow, and then choose Delay and Echo > Echo.

2. Compared to the previous delay effects, Echo has yet another way of setting the echo mix; each channel has an Echo Level control that dials in the echo amount. The Dry signal is fixed. When you’re using the echo effect, enter the following values for the left channel: Delay Time 545ms, Feedback 90%, and Echo Level 70%. Enter the following values for the right channel: Delay Time 1090ms, Feedback 70%, and Echo Level 70%.

3. Bring all Successive Echo Equalization controls all the way down (-15dB). By doing so, it will be easier to hear the effects of moving each slider.
4. Raise the 1.4kHz control to 0 (values above 0 produce runaway echo), and note how the sound is more “midrangey.”
5. Bring down the 1.4kHz slider, and raise the 7.4kHz slider to 0. Now the echoes are brighter.
6. Return the 7.4kHz slider to -15dB, and raise the 172Hz slider to 0. The echoes are now bassy.
7. You can vary more than one slider at a time to create a more complex equalization curve, as well as enable Echo Bounce to bounce each channel’s echo between the left and right channels.

Remove Echo After Effects

• This test is a good way of assessing whether your chest pain or discomfort is caused by coronary heart disease. It may be due to other problems.

• It is usually recommended if you are unable to do a treadmill exercise test or if your exercise test has been inconclusive.

• If we already know you have coronary heart disease or angina, dobutamine stress echocardiography can help the doctor assess the condition of your heart and plan further treatment.

• If you like help completing the form, please ask a member of our staff.

• Please ask about anything you do not fully understand or wish to have explained in more detail.

• Remember, you can change your mind about having the procedure at any time even after you have signed the form.

• The test can take up to half an hour to complete, and we ask you stay at the clinic for another half an hour afterwards. It is best that you do not drive after the test.

• It is also advisable to avoid alcohol, caffeinated drinks for the day after the test.

• Diagnose or exclude coronary artery disease.

• Assess prognosis in patients with known coronary artery disease.

• The test is performed by two specially trained health care professionals.

• The echocardiogram will be performed by a senior echo cardiographer who will also monitor blood pressure and Electrocardiogram (ECG) throughout.

• A cardiologist(heart doctor) will administer the dobutamine infusion and supervise completion of the test.

Serious or frequently occurring risks

• Serious side effects are rare. The risk of irregularity of heart rhythm with dobutamine is between 10 to 15 patients per 5,000 procedures.

• The risk of death is between 1/5,000 and 1/14,000..

• Reasonably common quickly reversible side effects with dobutamine include flushing, tingling, tremor, palpitations and desire to urinate.

• Atropine can cause reversible side effects such as dry mouth, dry eyes, and difficulty passing urine, dilated pupils and double vision.

• You will then be asked to remove your clothing from the waist up. Women will be given a gown to wear.

• Your heart trace (ECG) will be monitored throughout the test.

• A cardiac physiologist will attach ECG electrodes to your chest with simple medical tape. To ensure the ECG lead wires stay attached, we will clean your skin and prepare it for the electrodes. For men, it may be necessary to shave small areas of chest hair.

• A blood pressure (BP) cuff will be placed on your arm.

• The doctor will insert an intravenous (IV) cannula into a vein in your arm.

• You will be asked to lie on your left side for the duration of the test.

• The room lights will be dimmed to allow ultrasound images of your heart to be recorded. The sonographer will obtain resting images.

• A small amount of contrast agent is injected intravenously in order to improve image quality.

• Dobutamine infusion will begin at low dose and will be gradually increased every three to five minutes in order to speed up your heart. The test will continue until your predetermined target heart rate is reached. A small amount of Atropine may be given intravenously to allow your target heart rate to be reached.
