3 open source audio tools for creators
======
Finding good quality, open source audio samples can be a challenge. I've been getting increasingly into composition and creating music in my spare time, using the open source tool [Ardour][1] and the creator-focused distribution Ubuntu Studio. I've been looking for samples of specific sounds or loops to include.
I'm familiar with many tools to find images, but until recently, I hadn't come across a similar option for audio resources.
### Open source sound samples
Finding specific sounds can be challenging if you can't record them yourself. Several resources are available, but not many provide sounds under an open source license.
#### Freesound
Enter the incredible treasure trove that is [Freesound][2], a collaborative database of [Creative Commons][3] licensed sounds where you can browse, download, and even contribute.
You can find pretty much anything on Freesound, from the sounds of a sleepy tour bus on the road to a door opening and closing or a ghostly shriek. While Freesound mainly focuses on sound samples, there are also some loops on the site. Many sounds are licensed under Creative Commons 0, so you can do whatever you like with them from a licensing perspective. However, that's not true for all of them, so check the license before you use anything, as you may need to credit the creator.
The site allows you to check out the sample rate, bit depth, and channels so you can be sure that the sample will work with your composition, and it has a built-in rating system and download count. A waveform display allows you to get some insight into the character of the sound sample before you preview it.
The search filters on Freesound are not as strong as other sites. Sounds will sometimes be grouped into packs of similar sounds, like this one for [scary noises][4]. This can help you quickly grab a bunch of similar sounds to play with. The quality of the samples is variable, so you might need to clean up the audio on some samples. If you're feeling bored, there's even an option to select a random sound from the database—and trust me, some are very random! Freesound also has a community forum where you can participate and learn from others.
#### Nasa space sounds
If you are looking for some otherworldly sounds or want to snoop on the conversations between Earth and space, the [Nasa Space Sounds database][5] might be a great place to look. It's fascinating to explore the recordings from the various missions and listen in on the communications back and forth, some of which are narrated. Several recordings have different sounds from different space missions, from the Sounds of Mars from Perseverance Rover to audio from the Apollo missions.
Sounds from the Nasa site are released under the Creative Commons category Public Domain Mark 1.0, meaning that it is free of known restrictions under copyright law.
### Loops for music creation
If your focus is more on creating music, you might be looking for loops: short recordings of music that you can alter and tweak in your own compositions.
There are all kinds of sample packs out there from commercial sources, but there are also a lot of royalty-free loops available on [Looperman][6]. With over 200,000 loops uploaded by musicians, DJs, producers, and creators, there's everything from electronic dance music and trap to classical. There are also over 12,000 a cappella and spoken-word loops, and it's a great resource for finding things like bass lines or drum beats. You need to have an account to download, and you must download tracks before you can upload anything.
Looperman resources are not Creative Commons, but the site defaults to a similar concept: "All samples and loops are free to use in commercial and noncommercial projects," according to the site license, but "you can NOT claim copyright of those loops." A cappella and vocal samples are in a separate category, so checking the specific terms for any loop you consider using is important.
Each loop tells you the beats-per-minute, key signature (where relevant), and software it was created in. A waveform shows the character of the loop, which gives you a good idea of whether it is likely to work with your project. You can preview loops within the browser and leave comments for the creator. There is a lively community and many great resources to help you create your own loops.
### Get creative
I hope this gives you some ideas of where to find audio resources for your next project, and I look forward to hearing what you have created!

3 个面向创作者的开源音频工具
======
寻找优质的开源音频样本可能是一项挑战。我越来越多地使用开源工具 [Ardour][1] 和以创作者为中心的发行版 Ubuntu Studio利用业余时间创作音乐。我一直在寻找要包含的特定声音或循环的样本。
我熟悉许多查找图像的工具,但直到最近,我才遇到类似的音频资源需求。
### 开源声音样本
如果你不能自己录制特定的声音,那么寻找特定的声音可能会很困难。有多种资源可用,但在开源许可下提供声音的资源并不多。
#### Freesound
进入令人难以置信的宝库 [Freesound][2],这是一个 [Creative Commons][3] 许可声音的协作数据库,你可以在其中浏览、下载甚至贡献。
你几乎可以在 Freesound 上找到任何东西,从路上让人昏昏欲睡的旅游巴士的声音到开门关门的声音或幽灵般的尖叫声。虽然 Freesound 主要侧重于声音样本,但网站上也有一些循环。许多声音都是 Creative Commons 0 许可的,因此从许可的角度来看,你可以随心所欲地使用它们。但是,并非所有人都如此,因此在使用任何内容之前请检查许可证,因为你可能需要注明创作者的姓名。
该站点允许你检查采样率、位深度和通道,因此你可以确保该样本适用于你的作品,并且它具有内置评级系统和下载计数。波形显示可让你在预览之前深入了解声音样本的特性。
Freesound 的搜索过滤器不如其他网站强大。声音有时会被分成一组相似的声音,例如[可怕的噪音][4]。这可以帮助你快速获取一堆相似的声音来播放。样本的质量是可变的,因此你可能需要清理某些样本的音频。如果你觉得无聊,甚至可以选择从数据库中随机选择声音,相信我,有些声音非常随机! Freesound 还有一个社区论坛,你可以参与其中并向他人学习。
#### NASA 太空声音
如果你正在寻找一些超凡脱俗的声音或想窥探地球与太空之间的对话,[NASA 太空声音数据库][5]可能是个不错的去处。探索各种任务的录音并听取来回的通信是很有趣的,其中一些是旁白的。一些录音包含来自不同太空任务的不同声音,从毅力号漫游者的火星之声到阿波罗任务的音频。
来自 NASA 网站的声音在知识共享类别 Public Domain Mark 1.0 下发布,这意味着它不受版权法的已知限制。
### 音乐创作循环
如果你更专注于创作音乐,你可能正在寻找循环:你可以在自己的作品中修改和调整的简短音乐录音。
商业来源有各种样本包,但 [Looperman][6] 上也有很多免版税的循环。音乐家、DJ、制作人和创作者上传了超过 200,000 个循环,从电子舞曲和 trap 到古典音乐应有尽有。还有超过 12,000 首无伴奏合唱和口语循环,它是查找低音线或鼓点等内容的绝佳资源。你需要有一个帐户才能下载,并且你必须先下载曲目才能上传任何内容。
Looperman 资源不是 Creative Commons但该站点默认采用类似的概念根据站点许可“所有样本和循环都可以在商业和非商业项目中免费使用”但“你不能声明这些循环的版权”。无伴奏合唱和人声样本属于不同的类别所以检查你考虑使用的任何循环的具体条款是很重要的。
每个循环都会告诉你每分钟的节拍数、调号(如果相关)以及创建它的软件。波形显示循环的特征,让你清楚它是否可能适用于你的项目.你可以在浏览器中预览循环并为创作者留下评论。有一个活跃的社区和许多很棒的资源可以帮助你创建自己的循环。
### 发挥创意
我希望这可以让你了解在何处可以为你的下一个项目找到音频资源,我期待听到你创建的内容!
