# Introduction

This is an music analysis tool. We provide some basic music analysis method: Pitch estimation, Beat tracking, Chord recognition, Structure analysis, and Timbre analysis for users without  programming basis to analyze the audio in an easy way.

### Overview

The audioviz UI interface provides the following analyzing functions:

#### Basic Analysis

* [Waveform(matplotlib)](/musicai-ui-space-v2/basic-analysis.md#waveform-matplotlib)
* [Waveform(ploty)](/musicai-ui-space-v2/basic-analysis.md#waveform-ploty)
* [Single\_RMS\_analysis](/musicai-ui-space-v2/basic-analysis.md#single_rms_analysis)
* [Spectrogram](/musicai-ui-space-v2/basic-analysis.md#spectrogram)
* [Download RMS data](/musicai-ui-space-v2/basic-analysis.md#download-rms-data)

#### Pitch Analysis

* [Mel-frequency spectrogram](/musicai-ui-space-v2/pitch-analysis.md#mel-frequency-spectrogram)
* [Constant-Q transform](/musicai-ui-space-v2/pitch-analysis.md#constant-q-transform)
* [Chroma](/musicai-ui-space-v2/pitch-analysis.md#chroma)
* [Pitch class](/musicai-ui-space-v2/pitch-analysis.md#pitch-class)

#### Time Analysis

* [note\_detection](/musicai-ui-space-v2/time-analysis.md#node_detection)
* [Onset\_strength](/musicai-ui-space-v2/time-analysis.md#onset_strength)
* [Beat\_analysis](/musicai-ui-space-v2/time-analysis.md#beat_analysis)
* [Predominant\_local\_pulse](/musicai-ui-space-v2/time-analysis.md#predominant_local_pulse)
* [Static\_tempo\_estimation](/musicai-ui-space-v2/time-analysis.md#static_tempo_estimation)
* [Tempogram](/musicai-ui-space-v2/time-analysis.md#tempogram)

#### Chord Analysis

* [STFT Chroma](/musicai-ui-space-v2/chord-analysis.md#stft-chroma)
* [Chords Result(Default)](/musicai-ui-space-v2/chord-analysis.md#chords-result-default)
* [Chords Result(User)](/musicai-ui-space-v2/chord-analysis.md#chords-result-user)

#### Structure Analysis

* [Self-similarity matrix](/musicai-ui-space-v2/structure-analysis.md#self-similarity-matrix)

#### Timbre Analysis

* [Spectral Centroid](/musicai-ui-space-v2/timbre-analysis.md#spectral-centroid)
* [Rolloff Frequency](/musicai-ui-space-v2/timbre-analysis.md#rolloff-frequency)
* [Spectral Bandwidth](/musicai-ui-space-v2/timbre-analysis.md#spectral-bandwidth)
* [Harmonic Percussive Source Separation](/musicai-ui-space-v2/timbre-analysis.md#harmonic-percussive-source-separation)

#### Summary

* [Summary](/musicai-ui-space-v2/summary.md#summary)

#### Interactive mode

We also provide some interactive mode with histogram and waveform figures by ***ploty***.  You can choose to use an interactive mode by clicking the check box of `Use ploty` in the `dev` page.
