The PDF format is now a standard open format that isn’t just available under Adobe Acrobat. The format has evolved to allow for editing and interactive elements like electronic signatures or buttons. It was developed by Adobe so people could share documents regardless of which device, operating system, or software they were using, while preserving the content and formatting. We had difficulties with formatting issues, but hopefully with more time and effort, we will be able to resolve these issues.PDF stands for ‘Portable Document Format’ file. We are currently able to take a live recording and convert a base64 string and write it into an mp3. The next steps also include being able to successfully analyze a live recorded audio and hopefully also implement AR by showing the chords associated with desired song on a guitar or ukulele. After that, we will move on from identifying individual notes in our analysis to identifying full chords (strings of notes played together). Getting more accurate results with our frequencies will help us further focus on our analysis we would definitely utilize some of the functions from MATLAB's audio toolbox to help with this. The next step for Musical Note Recognition is to clean and remove the noise from the audio files to get more accurate results by pre-processing the signals. We learned how to implement the ACRCloud API, requests in backend, and we also became more familiar with the frontend. wave files and how to perform in depth analysis of the audio. We also learned a great deal about basic signal processing, like converting. We learned how to read spectrograms and how to identify the fundamental frequency along with the harmonic frequencies. We learned a great deal about sound waves and their composition, especially how Fourier Transforms can unravel multiple waves back into their original components. We learned quite a bit over this project. We are very proud of how we were able to get more familiar with javascript and learn more about backend and the ACRCloud API for Audio Recognition. We were able to understand basic signal processing with no prior knowledge, which is also a great achievement. Along with that, we are very proud of being able to identify the different frequencies on our spectrograms including the fundamental frequency and the harmonics. Overall, we are very proud of being able to understand how Fourier Transforms unravel the combination of sound waves back into individual sound waves/frequencies. We were able to live record the audio but we ran into many difficulties with analyzing that audio. Another challenge was understanding Fourier Transforms and how that related to the readings of our spectrograms and analyzing our audio.Īnother big challenge we ran into was live recording the audio and analyzing the audio. Some challenges that we had in our program was learning how to successfully use signal processing in 36 hours, however MATLAB's toolboxes helped with that quite a bit. We ran the MATLAB code from python from a local flask server and then displayed the notes and octaves on the website based on the timestamps. We outputted three vectors: one for the notes being played, one for the octave of said notes, and one for the time that each note took place. We wrote two functions, one to convert the frequencies found by the pitch function into musical notes, and the other to find which octave each note was in, in relation to middle C (C4) (262Hz). MATLAB's audio signal processing toolbox was helpful in analyzing and finding the fundamental frequencies of the audio signals. wav files in order to produce graphs of the Short Time Fourier Transform of the signal using MATLAB's spectrogram function. How I built itįirst, we created a static website in HTML and javascript which handled the inputs of the. After the mp3 is submitted, a snippet of the song is analyzed to determine the artist and song title using the ACRCloud API for Audio Recognition. The user can input an mp3 file and receive musical notes that correspond to the respective timestamp. After having countless struggles of not being able to find sheet music for songs that we love, we decided to create our own solution.
