When people discover Sonic Pi, one of the first things they learn is how simple it is to play pre-recorded sounds using the `sample` function. For example, you can play an industrial drum loop, hear the sound of a choir or even listen to a vinyl scratch all via a single line of code. However, many people don't realise that you can actually vary the speed that the sample is played back at for some powerful effects and a whole new level of control over your recorded sounds. So, fire up a copy of Sonic Pi and let's get started stretching some samples!

When you are practicing, you'll often find your mind is full of new exciting ideas - new musical directions, new sounds to try out, new functions to write, etc. These ideas are often so interesting that you might stop what you're doing and start working on the idea. This is another form of distraction!
あなたが練習している最中、気がつくと、音楽の方向、試してみたい音、書いてみたい関数など、新しい刺激的なアイデアで頭がいっぱいになることがあるかもしれません。これらのアイデアはしばしばとても面白そうなので、練習をやめてそのアイデアを作業してしまうかもしれません。これは、別な形の'気が散るもの'と言えるでしょう!

Practice tip #8 - keep a practice diary by your keyboard. When you get an exciting new idea, temporarily pause your practice session, quickly jot the idea down, then forget about it and carry on practicing. You can then spend some quality time thinking about and working on your ideas after you've finished practicing.
練習のヒント #8 - 練習日記をつける。刺激的な新しいアイデアが浮かんだら、一時的に練習セッションを停止し、素早くアイデアを書き留めてください。そして、そのアイデアのことは忘れて、練習を続けてください。そうすれば、練習が終わった後、そのアイデアを集中して検討したり作業できるのです。

Try to establish a practice routine which incorporates as many of these ideas as possible. Try to keep the sessions as fun as possible but be aware that some practice sessions will be hard and feel a little like work. However, it will all be worth it once you've created your first piece or given your first performance. Remember, practice is the key to success!
ここで紹介したアイデアを可能な限り取り込んだ練習ルーチンを確立するようにしてください。練習セッションは可能な限り楽しくしておくべきですが、ときには練習セッションは過酷で仕事のように感じることもあるでしょう。しかしながら、一度初めての作品を完成させたり、初めてのパフォーマンスを成功させたりしたら、練習はその価値があったと言えるでしょう。覚えておいてください、練習は成功の鍵なのです!

Slowing Samples Down

To modify the playback rate of a sample we need to use the `rate:` opt:
1788
sample :guit_em9, rate: 1
sample :guit_em9, rate: 1
1789
If we specify a `rate:` of `1` then the sample is played back at the normal rate. If we want to play it back at half speed we simply use a `rate:` of `0.5`:
1790
Notice that this has two effects on the audio. Firstly the sample sounds lower in pitch and secondly it takes twice as long to play back (see the sidebar for an explanation of why this is the case). We can even choose lower and lower rates moving towards `0`, so a `rate:` of `0.25` is a quarter speed, `0.1` is a tenth of the speed, etc. Try playing with some low rates and see if you can turn the sound into a low rumble.
