# HOW TO USE

## Pre-work
1. Listen to the target event before each task
2. Then, start labeling!
:::warning
**How To Label**
Select the region included the target event in an audio track, and add label to the region with the event name
:::

## Audacity
1. Open the software
2. Import the audio track you want to label 
3. Select the region and `ctrl`(&#8984;)+`B` to add labels
4. Go to `File > Export > Export Labels` and save as `{audio-name}.txt`

## Label Toolkit
:::danger
因為技術問題，請大家幫我使用 Google 無痕分頁開啟，謝謝
:::
1. Open the website (in **Chrome**)
    > http://ahg.ee.nthu.edu.tw/app/
2. Select the dataset and upload the **EVENT**
    (The audio tracks to be labeled are in the dataset already, you only have to upload the target event and it will help you in labeling.)
3. Listen and adjust the regions (`drag`, `resize`, `add`, `delete`)
4. Export the labels and save as `{audio-name}.csv`
:::info
You can seek to the onset or offset time by clicking the region (when not playing the audio)

點白色框框會跳到該區間的起始或結束，如果發生錯位(播放線與白框邊界未對齊)之現象，請大家包容一下，並可以於問卷內提出！
:::


## Notice
:::warning
You can label with the event name or its abbreviation, e.g., "TPE_Metro_BLine" or "B"
**BUT** please use the same format in both tasks
:::

1. For Manually labeling with Audacity:
Please record the labeling time of each audio track:
**START** when importing the audio and **END** with exporting labels
2. For labeling with Label Toolkit:
Please **DO NOT** change the candidate till you finish and export the labels. 
The system will **START** the timer when selecting a candidate and **STOP** at exporting labels.
