## What is AB Player?

Music Player for listening/study material. Fantastic learning aid for all language students.
This app is especially made for anyone who studies a foreign language and who listens to CDs which come with text books or podcasts.

• When listening to a CD, some parts can be difficult to hear correctly and you can't understand by listening only a few times. You want to and need to repeat that part many times.  Set playback area and you can repeat that particular area as many times as you want.  (A-B repeat playback).

• You can save the clip and listen to it later.
Send the clip as an email with attachment, or upload to Twitter or Facebook so your friends and teacher can listen to it too. (*)

• Adjustable playback speed.

• List up Recently studied albums.
• Track selection screen has a scroll bar so you can directly scroll to the track you need.  This is useful when a CD contains many short tracks.
• Directly move tracks from the player screen.  If your listening material tells you "Move to track number xx", you can move directly without going back to the track selection screen.


* Clipping is restricted to maximum 3 minutes.
* This player does not support to play back music with DRM (copy guard protection).

### 1/5 — Trouble

*2026-05-05, version 3.2.2*

This app worked just fine for a while now whenever I try to play a song on it I get a message that says it cannot play the song because it’s copyright protected by Apple. What’s going on?

### 1/5 — Do not work!

*2025-11-18, version 3.1.2*

The app just don’t work. I click to import a mp3 file and it does nothing. Nothing is loaded.

### 5/5 — mp3プレイヤーとして

*2025-01-21*

自前の音声ファイルがiOSでどんどん扱いにくくなっている中で、このアプリはシンプルかつ十分な機能をもつプレイヤーとして使えます。音楽プレイヤーとしても本来の語学用再生機としても大変扱いやすいです。大変良心的なアプリ開発をされていると思います。

### 4/5 — 音声が非常にクリア

*2023-08-28*

英語学習中で多数の再生プレーヤーをダウンロードしてますが、このアプリは群を抜いて音声がクリアに聞こえます。

操作も直感的でわかりやすい。

これで他のアプリから戻ったときに、今まで練習していた音声の再生画面に戻ってくれたらもっと便利なのですが…

今のところ、ライブラリや最近の再生リスト一覧になってしまうので、それだけが不便です。

### 5/5 — Excelente!! No he encontrado otra mejor! Felicidades!!

*2022-12-11, version 2.3.2*

En mi caso, me sirve mucho para estudiar canciones con mi guitarra, puedes bajar el Tempo, cambiar tonalidad, repetición donde gustes, maravilloso!!!

### 4/5 — ランダム再生機能もつけてほしい

*2021-10-24, version 2.2.1*

全体的に使いやすいかま、改善要望として2つ。 1. ランダム再生の機能もつけてほしい(これはデフォルトの音楽プレーヤーでできることだが、音声の再生スピードを遅く/速くした状態でランダム再生したいと思うので、こちらのプレーヤーでランダム再生できるようになるとありがたいです)。 2. アイフォンのデフォルトの方の音楽プレーヤーから読み込んだプレイリスト内の曲の順番がおかしな並びになってしまうバグが気になる。

### 4/5 — Error

*2021-01-19, version 2.2.1*

This is for sure the best app to repeat a stretch of any song, particularly good for musicians. BUT lately it is presenting some problems... sometimes the song stops playing (despite timer keeps running on), sometimes the “play” button just turn into “pause” itself, requiring you to click “play” again.

### 3/5 — simple

*2020-12-04, version 2.2.1*

this app is very simple. It requires more functions. simple and small. it is also good.

### 4/5 — 報告

*2020-07-21*

クリップをフォルダに保存する、の画面でキャンセルすると100%落ちてしまいます。
その他何かあればまた報告します。

### 5/5 — 最近の話題のものより良かった点

*2020-07-08, version 2.2.1*

語学用に以前ダウンロードしていたのですが、最近また必要に迫られて語学用のプレイヤーを再度比較してみました。結果、最近のもの（2020/7月時点）に比べてもなかなか優秀だと分かりました。

特に以下の２点。

・速度変化をさせた時の音声が自然です（他のものは、音声が明らかに不自然になるものがありますね）
・区間リピート位置が直感的にきめ細かく簡単に設定出来ます。再生中にリアルタイム焦りながらリピート区間を設定しなければならないという事がなく、スライドバーの音声ボリュームのグラフを見ながら息継ぎのちょっとした隙間を狙ってリピート区間設定する事も容易にできます。（スライドバーも、画面を横向きにすれば長くなるのでさらに微調整しやすいかもしれません）

最初のアプリのリリース時期が新しく無いせいか、語学プレーヤーで検索して比較レビューサイトに取り上げられているのを見つけるのは簡単では無いようです。
比較サイトに上がっていて評価の高いアプリも複数試しましたが、以前ダウンロードしていたこれが一番良かったですね。
何故人気が無い？のか不思議です。

有料版にすれば多分広告が消える思うのですが、広告もたいして気にならない配置位置です。

ライブラリは、iPhone標準のプレイヤーと同じで、自分はiTunes で取り込みました。
プレイリストもiPhone標準のアプリで設定できました。
