1. INTRODUCTION 1.1 Introduction This chapter includes an outline of the task, the purpose and objective of the work. It also gives a brief outline of the report. Singing is used to produces musically relevant sounds by the human voice, and it is employed in most cultures for entertainment or self-expression. The singing voice becomes immediately the main focus of attention when we listen to musical pieces with a voice part. Now a days, in multimedia technology various audio editor software’s are available. Mixture of singing voice and music accompaniment known as a song. Music recording are either monaural (single channel) or stereo (two channel) basis. Speech is an acoustic signal produced from a speech production system. Sound is a representation of an audio signal. 20 Hz to 20 kHz are the audio frequency range. The human auditory system has a better capability in separating sounds from different sources [1]. Speech separation is a very challenging task in signal processing. An Audio signal classification system detecting the audio type of a signal (speech, background noise and musical genres). A singing voice separation system has its applications in areas such as automatic lyrics recognition and alignment, singer identification, musical information retrieval, karaoke, musical …show more content…
Robust Principal Component Analysis (RPCA), which is a matrix factorization algorithm for solving low-rank and sparse matrices. Music accompaniment in a low-rank subspace. Repetition of music is a main parameter in a song. Singing voice is relatively sparse due to its variations or different pitch ranges within the songs. In system use Binary frequency mask for quality of separation results. Inverse Short Time Fourier Transform (ISTFT) is applied, in order to obtain the waveform of the estimated results and recover the original
Audition is a complex process that involves multiple areas of the brain. To be able to hear sound is just the beginning. Understanding speech and appreciating music requires an intensive and complex network of processes still yet to be understood. Many auditory processing deficits have been discovered with varying degrees of specificity and severities. A whole area of research has been dedicated to finding solutions to these auditory deficits that many ...

This report will be divided into six parts beginning with an introduction and ending with a conclusion.
As the recording process is completed one may divulge into editing their work. Editing is broken up into 3 categories: General, Medium, and Fine ("The Music Production Process: Step 6 Editing Music"). General Editing includes the basic notion of choosing each tracks individual level based on the loudness of others. Another step includes the correction of the singer’s notes, and or pitch correction. This is often done with auto tune programs such as Antares Auto-Tune EFX 2 (“Products”). Pitch correction is vastly use...
Polyphonic’s primary customers are record companies, producers and singers. This customer base has a common need is for an improved ability to predict how and which songs can become hits.
Sound is a type of longitudinal wave that originates as the vibration of a medium (such as a person’s vocal cords or a guitar string) and travels through gases, liquids, and elastic solids as variations of pressure and density. The loudness of a sound perceived by the ear depends on the amplitude of the sound wave and is measured in decibel, while its pitch depends on it frequency measured in hertz, (Shipman-Wilson-Higgins, 2013).
Three coordinate systems are utilized when attempting to locate a specific sound. The azimuth coordinate determines if a sound is located to the left or the right of a listener. The elevation coordinate differentiates between sounds that are up or down relative to the listener. Finally, the distance coordinate determines how far away a sound is from the receiver (Goldstine, 2002). Different aspects of the coordinate systems are also essential to sound localization. For example, when identifying the azimuth in a sound, three acoustic cues are used: spectral cues, interaural time differences (ITD), and interaural level differences (ILD) (Lorenzi, Gatehouse, & Lever, 1999). When dealing with sound localizaton, spectral cues are teh distribution of frequencies reaching teh ear. Brungart and Durlach (1999) (as seen in Shinn-Cunning, Santarelli, & Kopco, 1999) believed that as the ...

Thus, an open-room karaoke with a mini stage will be provided for the in house customers. Any client who wishes to show his / her talent can go up to the stage, choose a song, play the music and then start to sing. On the other hand, those clients who are shy to go on the stage can enjoy the music while having the
Song is an art that having created from a combination of word known as lyrics and rythem to ensure the beautiful melody. According to Allan (2014), people’s attitude are affected by their favourite song. People tend to have calmness when listening to music. Chen and Chen (2009) state that listening to the English song is considered as one of the effective teaching style to motivate elementary school students to learning English. People have a different taste of music. They can find the excitement of music through a different genre such as a cappella song, ballad song and nasyid song.

This chapter constituted of an introduction, an overview a problem definition, research objectives and variables.
Music comes in many forms. Whether if it is rock, pop, instrumental, indie, country, jazz, or another genre, everyone has a favorite. Music can be used to express oneself and bring enjoyment to life. Music can be live or recorded. Live and recorded music have many differences and similarities that can be noticed and loved depending on the listener. Live music can be expensive, but the experience is full of entertainment and emotion. Recorded music can be cheap, but vocals and sounds are edited in a studio. Despite these and many more differences, both types of music have similarities. Recorded and live music both bring enjoyment to listeners, connections among similar tastes, and can be found at parties, sporting events, and special occasions. Recorded and live music are unique in their own ways, but also similar in the way that they make a person feel.
Speech sounds can be defined as those that belong to a language and convey meaning. While the distinction of such sounds from other auditory stimuli such as the slamming of a door comes easily, it is not immediately clear why this should be the case. It was initially thought that speech was processed in a phoneme-by-phoneme fashion; however, this theory became discredited due to the development of technology that produces spectrograms of speech. Research using spectrograms in an attempt to identify invariant features of formant frequency patterns for each phoneme have revealed several problems with this theory, including a lack of invariance in phoneme production, assimilation of phonemes, and the segmentation problem. An alternative theory was developed based on evidence of categorical perception of phonemes: Liberman’s Motor Theory of Speech Perception rests on the postulation that speech sounds are recognised through identification of how the sounds are produced. He proposed that as well as a general auditory processing module there is a separate module for speech recognition, which makes use of an internal model of articulatory gestures. However, while this theory initially appeared to account for some of the features of speech perception, it has since been subject to major criticism, and other models have been put forward, such as Massaro’s fuzzy logic model of perception.
The data collected will be analysed and interpreted. The summary of the findings, suggestions and the conclusion will be given in the report.
