Linking Audio to Visuals and Applying effects P4 (d)

This is the music track which I used for my music video.The length of this music is about 2 minutes and 35 seconds.According to my storyboard,I have 4 different sections need to put into this music videos.2 and 35 seconds would be really compact.Therefore,I download another version of this music which is the pure piano part.

I cut the song and I used the first 20 seconds to put into my music video which is the beginning.

This is the final version of my music.The piano version allows about 20 seconds extend and that means I have more space to put more videos to link and match with my 4 different sections storyboard.

Next,I didn't took any lip singing scene in these videos.Therefore,I muted all of the Audio 2 (the sounds from the videos).

I added a lowpass to the first music track.(the piano version with 20 seconds at the beginning of the video).This effect would allow the song sounds more suitable as a starter.

The low pass would also decrease the volume and sounds for the first starter piano music.This would allow the main track sounds stronger.

The meaning and purpose of Audio

Audio is sound within the acoustic range available to humans. An audio frequency (AF) is an electrical alternating current within the 20 to 20,000 hertz (cycles per second) range that can be used to produce acoustic sound. In computers, audio is the sound system that comes with or can be added to a computer. An audio card contains a special built-in processor and memory for processing audio files and sending them to speakers in the computer. An audio file is a record of captured sound that can be played back. Sound is a sequence of naturally analog signals that are converted to digital signals by the audio card, using a microchip called an analog-to-digital converter (ADC). When sound is played, the digital signals are sent to the speakers where they are converted back to analog signals that generate varied sound.

Audio files are usually compressed for storage or faster transmission Audio files can be sent in short stand-alone segments -.. For example, as files in the Wave file format In order for users to receive sound in real-time for a multimedia effect, listening to music, or in order to take part in an audio or video conference, sound must be delivered as streaming sound. More advanced audio cards support wavetable, or precaptured tables of sound. The most popular audio file format today is MP3 

In my product,I choose the song 'How long will I love you' is a romantic song,therefore,I should allow the audio played relatively slowly to match the video image I took.

The Adobe Prmiere Pro app allows me to change the original music,such as speed up part of the music or add effect to it.
